Unit/Lesson retrieved from LOR doesn't contain content?

Options

I published a single unit to the LOR. When I published it to a different course:

  1. The text in the Unit and nested Lessons was missing (I could re-add it after the fact)
  2. The HTML topics nested beneath the unit/lessons have content.

Is this expected behavior? I would expect that the text in the unit/lessons would be included when published to the LOR.
