Compiling problem

Hi, I’m using Scrivener to compile my novel into to a Word document on an HP laptop. Recently, the margins for chapters 56-64 (the end of the novel) are shifted so that they no longer fit on the page, cutting off the text on the right side. The centered chapter headings are also shifted to the right, as though the new ‘center’ of the page has itself been shifted. All of the earlier chapters are compiling fine. This has never been a problem before. Anyone have any suggestion how to fix?

thanks

Edit: I just realized that for some reason the compiler is INDENTING the Right Margin by -1.98 inches for those pages. Why would it do that?
