Library adds all single folders instead of the main one

When I add my music folder to babe 1.2.1, then every single folder below the music folder is added. I would expect to see just the main folder in the library and not hundreds of single ones.

If I want to delete a music folder, I would have to delete every single folder manually instead of just removing the main folder.

The box containing the sources doesn't scale either and you need to scroll a lot to to see the full path.

Besides this babe crashes on Plasma-Wayland when scanning the library.:
