Hello @AlL,
after solving a ticket by changing status to "done" (Fertig) even the workflow is correctly set, that "done" is the last status so that ticket is closed, all tickets are still available in "toDo" (Alle offenen Anfragen).

I expected, that the queue only displays tickets which has to be solved, and after solving they will deleted or moved to another "board", e.g. archive.

Best regards
Sascha
