As I said - we've been generating Help for several years now. The method hasn't changed.
I selected Heading1, 2, and 3.
For some reason, RH stopped breaking down the document into topics.
Sometimes the environment can mysteriously change so pagination was the place to start!
The next thing to check is the headings in the specific document Word. I've seen quite a few posts where further investigation reveals that the "headings" were in fact styles the author had created that were not the heading styles that come with Word. Is this possible here, is it one of your documents or someone else's creation?
Try creating a new project and importing a document that has imported correctly in the past. Does it still do so or does it too display this problem?

Tried a new project in RH and a new document based on Word's Normal
template and built-in styles.
Same problem. Seems like a problem in a RH or Word patch.
If you encounter it, try removing Word security patch. Microsoft say it's not their problem. We opened a bug report for RoboHelp.
