I managed to delete forwarding emails from an email account leaving the forward only checkbox checked, so the emails are not saved and also not forwarded.. I was also able to reproduce the error.
This will fix that: if no forwarding emails set, it will remove the checkbox of "Do not store forwarded mail".
