Duplicate UUID after delete add-on, no new submission possible

I uploaded a version to add-on hub for signing and then deleted it, which looks like causing a garbage left, and I cannot submit the same add-on again.

It complains following and disallow me to submit for review. Please kindly help.

Your add-on failed validation with 1 error.Duplicate UUID found.

Thank you. email amo-admins@mozilla.org works, the issues was resolved soon after that.

What was the reason for deleting it?

I was moving it to another account.

Ugh, there is no need to do that, you can change the owner easily in your developer hub. Next time, please ask before you delete your add-on. You made me review your add-on for nothing.

Oops, I don’t know about that, sorry.

While submitting add-on, I am getting error “Your add-on failed validation with 1 error.Duplicate add-on ID found.” Kindly help in this issue.
