custom master page, reverting back to left/right

[Linda Camp]

Milan,
Is it possible you have a Master Page map applied on your reference page?  To check, go to View > Reference Pages. Scroll down until you find the UnstructMasterPageMaps.  If this is defined for left and right master pages, and you choose to Apply Master Pages when you generate your book, the master pages are reapplied. For information about what the table means, search for "Assigning master pages" in the FM online help.
HTH,
Linda
