I use Mini-Tocs (depth 2, no other custom styling, "Use TOC Depth" enabled) on my chapter splash pages. For almost all of the chapter pages, only the first one or two items in the mini-toc appear. In addition, a single one of the Chapter Splash minitocs works and displays all 5 items. This is especially baffling because the same snippet is used in each place, and they all have the same structure underneath them. Try as I might, I can find no pattern to why that one minitoc works properly and all the others do not.
Few misc notes:
- These same mini-TOCS works flawlessly in PDF and online output.
- The Mini-tocs are located in H1 topics. Following them is a list of H2 topics, most of which have several H3 exercises in them
- These H2 topics have their own mini-tocs for the H3 items that they contain. These, also, work fine.
- Changing the order of the H2 exercises only changes which one H2 appears in the mini-toc.
- Generally speaking, the mini-TOCS stop adding items after the first book-level H2
