[SOLVED] Deleted status

Hi all,

I intentionally deleted a status I created associated to invoices and updated the workflow accordingly.
Unfortunately, I didn't noticed that some of the invoices already registered had the deleted status assigned. I supposed that I could update these invoices according to the new workflow but when I try to update the status of these invoices the only option ProjeQtOr gives me is the id of the deleted status.
Is there any way to update these invoices with a "blank" status according to the new workflow or the only option is to create new invoices and associate the new status?
Thank you in advance.
