Qt Creator adding some kind of configuration lines to current qml file on save, how to disable this behaviour?

[jackyBlinkerEye]

When I open my qml file with designer tab, and after changes been made if i save the file qt creator is automatically adding form editor configuration bottom of the page. I want to disable this functionality. It's been a while I'm looking for a solution but I can't even find what those lines called.
Note: till now only thing I found related to those added lines is "Annotations". Annotations are also being add to that part of the file but seems like this is the only thing is common.

Mentioned addition is someting like this:

/*##^##
Designer {
    D{i:0;formeditorZoom:0.9}
}
##^##*/
