SpinBox showing a frame

[ACaldas]

Hi all!
Could anyone tell me how to get rid of this blue square that appear when I try to edit the value of spinBox via keyboard?

My SpinBox:

import QtQuick 2.0
import QtQuick.Controls 2.12

SpinBox {
    id: sb1
    from: 0
    value: 0
    to: 100 * 100
    stepSize: 1

    property int decimals: 2
    property real realValue: value / 100

    width: 100
    height: 18
    editable: true
    antialiasing: true
    anchors.leftMargin: 0
    anchors.topMargin: 0
    rightPadding: 30
    leftPadding: 30
    padding: 0
    font.pointSize: 8

    validator: DoubleValidator {
        bottom: Math.min(sb1.from, sb1.to)
        top:  Math.max(sb1.from, sb1.to)
    }

    textFromValue: function(value, locale) {
        return Number(value / 100).toLocaleString(locale, 'f', sb1.decimals)
    }

    valueFromText: function(text, locale) {
        return Number.fromLocaleString(locale, text) * 100
    }
}

in My Main.qml:

CustomSB {
                                    id: spinX1
                                    objectName: "prostDim1"
                                    width: 100
                                    anchors.right: x12.left
                                    anchors.top: parent.top
                                    enabled: !aaa.checked
                                    editable: true
                                    stepSize: 10
                                    anchors.topMargin: 12
                                    anchors.rightMargin: 5
                                    onValueModified: result7.text = calculateVolume (spinX1.value, spinX2.value, spinX3.value)
                                    decimals: 1
                                }
