Combine request (doesn't work for some reason)

[Tny]

People We Meet on Vacation
and
You and Me on Vacation
are the same book with a title change:

For some reason when I click combine, I get the notification that it's done and it will take up to 15 minutes but nothing happens, would be grateful if a superlibrarian could look at this, thanks!

It doesn't work any better for superlibrarians. You just have to keep trying, and keep trying, and keep trying.......................

Ok, thanks. I'm currently in a temporary combine limit but I'll try again later then:)
