So, I made some experiments.

Obviously, turning the orientation of the tablet (portrait > landscape) automatically adds the [OK] button as well as hitting [select all] or [deselect all] (in German). Taking a screenshot automatically adds that button, too - but after taking the snap shot (Version C below).

It turned out that there are three variations of such a select window:
a) list without [OK] button at the end;
b) list with [OK] button at the bottom - comes when I hit [select all] or [deselect all];
c) list with [OK] button plus additional space at the bottom - comes imediately when opening the list a second time. That version follows automatically when having effected a screenshot!

For now, it happend with the Genre, the Type, the Keys, the Interpretes or the Composers field. Not with the Collection or the Custom field list. It's more often than I thought: It's reproduceable, I just need to close the edit action and open another song to get the same problems.

I'm not sure if that happens in the import mode, too. Usually, I encounter that problem when being in library view and starting to edit a song or when hitting the edit function while in sheet view.

Maybe, I need to add that I use an OS mode without the 3 Android soft buttons but gestures instead for the basic OS functions.
