I need help updating my book cover on Goodreads. > Likes and Comments

Can someone please tell me how to update my cover on Goodreads? When I go to edit the cover it says only librarians can alter the cover. I need to change my cover to match with Amazon. Thank you for any guidance you can give me.

Covers for existing books cannot be changed, you have already added an alternate cover edition which is the correct action.
If you want the new image to show on your author page edit the new edition and select it as primary/default edition.
