I am trying to create a singular HTML5 output that is a combination of 3 book files (one 'master' book with 3 child books). When I do this the heading levels in the TOC pane are not respected resulting in a flat (non-indented) output. Also, the autonumbering is omitted and the topic names list the file names instead of what’s written in the FM files.
Now, when I create HTML5 output on each individual book, its formatted correctly (headings, autonumber, etc.) and the output looks great; its only when I add each book as a child book and then create the output using the 'master book' does the TOC pane not have the correct heading levels, autonumbering, file names.
The source file are in FrameMaker unstructured format. The books are made up of Chapter files, an FM generated TOC, and Index. I'm also using a CSS file for automapping the styles. We are using FrameMaker 2019, latest build.
