Issues with dragging and dropping sub-presentations to scene view

Dragging a uip or qml file from project palette to the scene view causes a few issues.

1. The Set Sub-Presentation dialog window displays wrong text on the buttons (Yes/No when they should say Layer/Texture), actions are correct though.

2. When I close the dialog window by pressing Cancel or X, window will close and reopen.

3. Sometimes when I drag and drop, nothing happens.

These issues did not happen the first times I tried, but now it happens every time in every project also after re-start. It might have been triggered when I dragged and dropped an qml file.
