Goodreads Librarians Group discussion

My name is Phill Featherstone. I have a new cover for my novel Tideswell (paperback ISBN 9781068189609, ebook ISBN 9781068189616). I asked for the new cover to be added and it does appear on Goodreads but is hard to find. The old cover still shows on my book page and comes top of the list in a search, although the new cover is there much further down the list. When I click on the cover there's no edit option.
How do I make the new cover the primary edition? How can I get it to appear in a search in preference to the old one.
I'm keen to advertise this book on Goodreads but can't until the cover issue is solved. Please help.

Edit the edition with new cover and select it as primary/default edition. Librarians cannot do this for you
