When the command line is used to run a flow, an "errorlevel" of 0 would return even if the command failed in some versions.

A partire dalla versione 2020.3.3 per ogni filtro di valori discreti avanzato esistente nel flusso degli utenti o in un nuovo flusso creato in passaggi raggruppati l'annotazione non verrà visualizzata nella scheda del profilo come previsto per vedere o effettuare eventuali modifiche. Per aggirare la situazione si deve utilizzare il riquadro delle modifiche a sinistra o il riquadro del flusso nella parte superiore in modo da accedere all'annotazione/modifica del filtro dei valori discreti avanzato che si era apportata.
