3. If I push the left mouse button for the back icon in the systemsettings window the following terminal outputs occurs:

qt.quick.touch.target: QQuickTapHandler(0x556c263e5490) pointId 0 is missing from current event, but was neither canceled nor released
qt.quick.touch.target: QQuickTapHandler(0x556c263e5490) pointId 0 is missing from current event, but was neither canceled nor released
qt.quick.touch.target: QQuickTapHandler(0x556c263e5490) pointId 0 is missing from current event, but was neither canceled nor released

OBSERVED RESULT
back button in in systemsettings window shows no function, sub menus couldn't leave to main tree

EXPECTED RESULT
submenus in systemsettings should be leave
