GraphsView: Labels in Bars in a BarSeries stay after clearing the series

[Dizarc]

Currently I have a GraphsView with a BarSeries inside it.
The graph has Values on the Y axis and Dates on the X axis and It supports filtering by different variables such as dates.

Since i want the value to be clearly viewed above the bars i have used the properties regarding labels inside the BarSeries. But every time I filter the data some of the old values still show. I have tried using clear and append for the new data, I have tried turning the labels visibility off and on, I have also tried removing the series from the GraphView and adding it back with the new data which works but adds a different type of issue where the series is shown for a split second and gets removed after.
The weird thing I have seen though is that the data is shown normally every time i filter the default launch way and any old labels get removed.

I have also attached screenshots to show the issue.

Using QtQuick 6.8 and QtGraphs Windows 11 MinGW

Graph used in the application:

GraphsView {
      id: graphsView

      antialiasing: true

      Layout.fillHeight: true
      Layout.fillWidth: true

      axisX: BarCategoryAxis{
        categories: LogData.categories
        subGridVisible : false
        gridVisible: false
      }

      axisY: ValueAxis {
        min: 0
        max: 200
      }

      theme: GraphsTheme {
        backgroundVisible: false

        seriesColors: Style.inputBoxColor
        borderWidth: 2
        borderColors: Style.borderColor

        grid.mainColor: Style.inputBoxColor
        plotAreaBackgroundColor: Style.backgroundColor

        axisXLabelFont.pointSize: 10
        axisX.labelTextColor: Style.textColor
        axisX.mainColor: "transparent"
        axisX.subColor: "transparent"

        axisYLabelFont.pointSize: 10
        axisY.labelTextColor: Style.textColor
        axisY.mainColor: Style.textColor
      }

      BarSeries{
        id: bars

        labelsVisible: true
        labelsPrecision: 0
        labelsFormat: '<font color="' + Style.textColor + '" size="4">@value</font>'
        labelsPosition: BarSeries.LabelsPosition.OutsideEnd

        Component.onCompleted: bars.append(LogData.generateSeries("all", -1, -1, "day"))
      }
    }

I have filtering done with other variables but here is simply filtering done by dates:

ButtonGroup{
      id: radioGroup

      onClicked: {
        graphColumn.sizeSelected = -1
        sizesComboBox.displayText = qsTr("All")

        typesComboBox.currentIndex = -1
        typesComboBox.displayText = qsTr("All")

        clothesComboBox.displayText = qsTr("")

        bars.clear()
        bars.insert(0, LogData.generateSeries("all", -1, graphColumn.sizeSelected, radioGroup.checkedButton.text))
      }
    }

    RowLayout{
      Layout.alignment: Qt.AlignVCenter

      Text {
        text: qsTr("Filter by date:")

        color: Style.textColor
        font.pointSize: 12
      }

      CustomRadioButton {
        checked: true
        text: qsTr("day")
        ButtonGroup.group: radioGroup
      }

      CustomRadioButton {
        text: qsTr("month")
        ButtonGroup.group: radioGroup
      }

      CustomRadioButton {
        text: qsTr("year")
        ButtonGroup.group: radioGroup
      }
    }

Getting the data works normally as intended but I am putting it out here just incase:
LogData.h:

class LogData : public QObject
{
    Q_OBJECT
    Q_PROPERTY(QStringList categories READ categories NOTIFY categoriesChanged)
public:
    explicit LogData(QObject *parent = nullptr, QSqlDatabase db = QSqlDatabase());

    QStringList categories() const;

public slots:
    bool log(const int &cId, const int &tId, const QString &sName, const int &value);
    QBarSet* generateSeries(const QString &filterType, const int &filterId, const int &sizeId, const QString& dateFormat);

signals:
    void categoriesChanged();

private:
    QStringList m_categories;
};

LogData.cpp:

QBarSet *LogData::generateSeries(const QString &filter, const int &filterId, const int &sizeId, const QString &dateFilter)
{
    QBarSet* barSet = new QBarSet("Count");

    //SQL date grouping format
    QString dateFormat;
    if(dateFilter == "day")
        dateFormat = "strftime('%Y-%m-%d', changeDate)";
    else if(dateFilter == "month")
        dateFormat = "strftime('%Y-%m', changeDate)";
    else if(dateFilter == "year")
        dateFormat = "strftime('%Y', changeDate)";

    QString queryStr = "SELECT " + dateFormat + " as period, SUM(changeCount) FROM ChangeLog ";

    QStringList whereClause;
    if(sizeId != -1)
        whereClause.append("sizeId = :sizeId");

    if(filter != "all"){
        if(filter == "type")
            whereClause.append("typeId = :typeId");
        else if(filter == "item")
            whereClause.append("clothingId = :clothingId");
    }

    if(!whereClause.isEmpty())
        queryStr += "WHERE " + whereClause.join(" AND ");

    queryStr += " GROUP BY period";

    QSqlQuery query(queryStr);
    query.prepare(queryStr);

    if(sizeId != -1)
        query.bindValue(":sizeId", sizeId);

    if(filter == "type")
        query.bindValue(":typeId", filterId);
    if(filter == "item")
        query.bindValue(":clothingId", filterId);

    //dates for X axis
    QStringList xDates;
    if(query.exec()){
        while(query.next()){
            QString period = query.value(0).toString();
            int count = query.value(1).toInt();

            xDates.append(period);
            *barSet << count;

            qDebug()<< period << " " << count;
        }
        qDebug()<< "================";
    }else{
        barSet->deleteLater();
        qWarning()<< "Error creating series...";
        return NULL;
    }

    m_categories.clear();
    m_categories.append(xDates);

    emit categoriesChanged();

    return barSet;
}

QStringList LogData::categories() const
{
    return m_categories;
}

Screenshots for reference:
on Launch(filter by days):

filter by month(one wrong label shown):

filter by year(many old labels shown):
