My section 2 header has the wrong page number on the last page of the section. I'm sure I must be overlooking something really simple and obvious. I have a relatively simple, short document set up like this:

Title Page (no header or footer, no page number)
- section break -
Table of Contents (section 2 header with page number "X of Y")
- page break -
Body of document (section 2 header and page numbers continue)
- section break -
Appendix (section 3 header with page number "A-X of Y")

The header begins on the ToC page, numbered as "Page 1 of 6." The page numbering continues correctly until the last page of the body, which says "Page 2 of 6" instead of "Page 6 of 6."

-There is no a section break before the weird page.
-The header still says "Header - Section 2-" and if I change anything in it, it affects all the pages before it, so I don't think there's a hidden section break anywhere.
-I tried deleting and reinserting the page number field.
-I accepted all changes and stopped tracking for the document, but that didn't fix it.

What else should I check?
