Private (in company) add-on, Duplicate found error

Hi, I believe one of our contractors signed a add-on we distribute privately in our company previously. I just went to get an updated version signed and get the duplicate addon id found error. This addon is generated by an enterprise product we use, so I hope there’s a way to simply either move the existing addon id to my account, or remove it entirely so I can proceed (vs. having to play with addon details in the package). Hoping for advice or help - thx in advance!

Please email amo-admins AT mozilla DOT org with the details and we’ll help you there.
