While uploading a new add-on developed by us, we are getting this error: Your add-on failed validation with 1 error. Duplicate add-on ID found.

I had uploaded this add-on from a different ID to test the uploading process, after which I deleted the add on from that ID. Still the error is showing. Please help.
