Unable to add new editions of my books > Likes and Comments

I have received the rights back to my novels. The 1st editions are listed on my author page, but I cannot add the 2nd editions with new covers, new imprint, and new ISBNs. I get an error message that they are already on my page even though the ISBNs are different.

If you tell us what the ISBNs are we can look into it, but if they're not here there's no reason you shouldn't be able to add them. How are you trying to do it?

Archiving due to non-response.
