FrameMaker 10 to PDF making Funky Bookmarks

[Trish Castin]

I have both portrait and landscape .fm files in my book.  I've seen the postings about not using Save As PDF and also about making sure tagging is turned on.  I've now discovered a new issue...

The Bookmarks in the PDF for the Landscape pages show up as a sublist of the previous chapter.

Example:

Chapter 1: ABC (portrait chapter)
    1.0 Introduction
    1.1 Next Heading 1
    Chapter 2: DEF (landscape chapter)
Chapter 3: GHI (protrait chapter)

They use the same Heading tags in the .fm files.

Anyone know how to fix this one?

Thanks in advance,
Trish
