Seems that I have been here before LOL

I am remixing a book in my Sandbox to straighten out the order in the imported book.

I copied the book from my Sandbox - otherwise I couldn't see it in the remixer.

When I generate the new book it shows Front Matter and Back Matter pages..all the other pages are present as I can follow the links from Front Matter....but they do NOT show up on the book page

How do I get ALL my pages to show??

Thanks

Pat
