Table of Contents missing paragraph styles
Hi, I'm trying to create a table of contents but InDesign is not picking up on all the paragraph styles throughout the book.
Here are the documents in the book panel:

And here are my TOC settings:

Each of the "book 1/2/3/4", "introduction", and "acknowledgements" documents should have many instances of these paragraph styles, but when I generate the TOC all I get is this:

One lonely instance in the acknowledgements.
So I tried adding my standard paragraph style to the TOC (which should make my TOC almost as long as the whole book) just as an experiment and again, InDesign only gave me instances of the chosen paragraph styles up to and including the acknowledgements document but nothing beyond.
Perhaps there is a way to ask ID to include all documents by default? It seems to be missing the bulk of my book--everything after the acknowledgements--in generating the TOC.
Stumped.
