Reply To: TOC missing titles

I’m having this problem for the first time today. I’ve used InDesign since version 1.0, and was an Adobe Certified InDesign Instructor for about 20 years. I’ve created many dozens of Books, with ToCs, and never had an unsolvable problem. Using a book, the ToC picks up info from the first 6 documents, but not the 7th. I’ve checked and rechecked the styles applied, removed and re-added the doc from the book, and done everything else (even things that shouldn’t make a difference).

I’m stumped, and would love to know if others have had this problem.
