Unable to add existing book to my dashboard > Likes and Comments

Hello,
I have been through the process of adding (linking) a book to my author dashboard, and my book is already in the database. However, when I select it from the list, it opens a new page and doesn't autocomplete the details. I don't want to add the book again. In fact, there are two versions in the database - one doesn't have a cover, and I believe should be deleted. Could someone help me please?
This is the link to the one which needs to stay and be added to my dashboard.

Thank you very much.

Moved to your profile. Use the Book Issues folder next time. This one is for adding new books.
