This is a rather complicated issue, I'm fighting against a "feature" of Acrobat.
I'm working with a 500-page book and I need to change / remove about 30 headers from non-sequential pages.
Whenever I change or remove any header, however, Acrobat recognizes the change, and replicates it on every other similar header in the book.
Is there any way to un-link the headers or disable this "feature" so that I can make changes to a few specific pages?
Use the link "Page Range Options...".
