Hallo,
ich habe das Problem, dass ich in der Version 2.0.4 seit gestern kein Angebot mehr speichern kann. Beim Klick auf den Button "Speichern" passiert gar nichts. Wird dann ein zweites mal geklickt die Meldung, dass es sich nicht um die nächste freie Nummer handelt.

Für Eure Hilfe bin ich sehr dankbar.
