how to combine books in Goodreads?

[IW Ferguson]

I'm often mystified by everything Goodreads. I thought my one GR review had disappeared, but it turns out I have two listings on Goodreads, one for the paperback and one for the ebook. Seems like I can and should combine them, but when I click the link to do so, I see both listings, but only one of them has a checkbox next to it. If I click the "combine" button, I get an error saying I have to select more than one, but I can't. Thanks.

ETA: I found the Librarian group, and came back here to delete the topic, but it says I can't. Oh well. I'm off to try joining that group so I can make the change.

I was about to say to find the librarian's group on Goodreads - I've found them really quick to respond, so hope it's sorted soon for you.
