Adding a book to my Author Profile > Likes and Comments

Hello, I have been trying to add two of my recent books to my Author Profile - The Midnight Man and A Death in the Afternoon. I fill in the required form correctly and the system tells me that these books already exist on the database. I know this, they are included on Goodreads, but I cannot get them linked to my Author page. Can you help me, please?

This request does not involve the adding of new books/new editions to the Goodreads database, so it is in the wrong folder..
See Where should I put my request? (folder overview)

Please MOVE your topic to the correct folder Book & Author Page Issues by clicking the (EDIT) button next to the topic's title and picking the target folder from the pulldown list (only available for desktop/laptop, not in the app).

P.S.:
Links to the books already on Goodreads that need to be moved to your profile would be helpful.

Done, closing.
