I think we will need a minimal example (MWE) of this to diagnose. The 
LyX file should be self-contained if possible, so you try cutting out 
illustrations and other external matter. If the contents is not for our 
eyes, feel free to substitute "blah blah blah" or whatever, so long as 
when you compile the MWE the page numbers remain buggered.
