Page Numbers Bug in LR Book Module

I am working on several books at a time in the Book Module in the latest version of Lightroom 5.7.1

I want page numbers in one or two of the books, but not in all of them.  When I check Pages for one book, they all show up in the other books as well.  If I go to the book where I don't want Page numbers and UNCHECK Pages, then pages disappear in the book where I do want them.

Anyone else with the same problem?  It seems like checking Pages affects all books at the same time. This is really bad as I also have older books in the catalog which I do not want modified by a bug.

Thank you.
