Some troubleshooting ideas to look for are:
- Topics at a level 1 in the book structure should contain text content. No empty topics!
- Interactive slides must have the correct number of sub topics for their type. Ensure that flip cards have an even number of sub topics, carousels have the same number of sub topics as images, etc. See Structuring slides and their elements for all slide type requirements.
- Knowledge Check slides (Multiple Choice Single Selection or multi-Selection) output as straight text when a slide previous in the structure has no content (see first bullet).
