How can I add to my author page two books of mine that are listed as Unknown Author?

[Fabrizio]

Hello,
I recently claimed my author page and I would like to add these two books:
https://www.goodreads.com/book/show/2...
https://www.goodreads.com/book/show/1...
which are both listed as “Unknown Author” but have my name on the cover, are included on my personal website and are also listed as mine on Amazon: https://www.amazon.it/s?i=stripbooks&...
I tried with “add books”, but my update attempt was rejected because the two books are already catalogued according to the ISBN code – but, in fact, with incomplete data and without my name etc.
How should I proceed?
Thanks in advance to everyone.

Done. It might take a while for updates to show.
