Page navigation in Acrobat does not match page numbers in the document

I have a document in both Framemaker format (server.book) and PDF (server.pdf).  When I view the pdf file in Adobe Acrobat, the page numbers appear correctly on the document itself, but up in the Page Navigation window within Acrobat the pages number doesn't match.

In the beginning of the book I have Title page, a Table of Contents, and a Preface that all use lower-case roman numerals.  However, when viewing this document via Acrobat, the Title pages show up as i, and ii, but then the Table of Contents and Preface show up as pages 1 - 8 instead of iii - x in the page navigation window.

I can't figure where this discrepancy is originating. 

Please help.
