okay, its working but only if you choose restrictions > group by> track.... if you choose restrictions > group by>"album" the album tracks are listet in the exceptions, but still shown in the playlist
update: also if you have ticked "display first few tracks only" in the "album and tracks" view, you have to expand the album first. Then you can click on the artwork, all tracks get selected and you can delete them from the playlist. If you dont expand the album and you click on the artwork, just the displayed tracks are getting deletet. Maybe because only the displayed tracks get selected?
