Error while releasing/"freigeben" of a sheet/"Folie"
If I select a single sheet from my sheetset ("Vortragsfolien"), toggle the release sheet ("Folie freigeben")-Button, switch to my next sheet and back, the old state of the button is displayed (if I switch it off, turn to the next sheet and back, it's displayed as on).
The same problem occurs while blocking ("sperren").
The real state is shown if you leave the Edit-View and enter it again. This is very confusing.
