Multiple book URLs for same book but not showing up as multiple editions in dashboard > Likes and Comments

Hello! I've found multiple URLs for one of my books, each URL with different reviews, but in my dashboard, I only see one edition and therefore cannot combine. I am trying to combine the following URLs/editions so that reviews aren't splintered:

URL #1: https://www.goodreads.com/book/show/2...

URL #2: https://www.goodreads.com/book/show/2...

URL #3: https://www.goodreads.com/book/show/2...

Done. This did not involve adding new books.
