Table of Contents blank
I'm so confused. I have an academic catalog I'm working on that I update once a year with new courses, professors, etc. It is in a book with 18 documents. For some reason when I try to update the table of contents this year it just gets wiped out. It goes from a 5 page table of contents to nothing. No overset text. It's as if InDesign doesn't see any of the 4 paragraph styles the TOC is supposed to pull in, but I went through and made sure that there are. I could use any help on this.
Here are several screenshots for reference.
I usually consider myself at a somewhat advanced level in InDesign, but it could be something simple that I'm missing, so any ideas are welcome!
