I have renamed the UGC cinema as Cineworld and have made a note about its previous name.
FYI, just because there are no books currently at a location, it doesn't mean that there have *never* been books there. It's possible that the books released there previously have all been caught, which would result in the "No Books Found" message. It's not possible to actually delete a zone (just hide it), but if it were possible, it means that the history of those books would also be lost.
PS I see that you're a new member. Welcome to Bookcrossing. I hope you release many books in Bedford!
