When I insert a page or pagination changes within my book, the headers\footers set in my masters center on the spread. The error does not occur when I insert a page that does not have a text box for the main content of my page. When I reapply my master an error pops up that the page size of my doc has changed from the master. It also does not occur when in pages that I did not build. I've gone over my page settings with a colleague and nothing appears to be different. I've tried saving as an IDML and the error persists. Hoping that there is something stupid that I missed.
