Quiz master glitch

A bug I've experienced in all revisions of Storyline, and in all my courses: Eventually, the quiz master will stop formatting quiz questions correctly.  The symptoms include:

- Bullets jammed up against the choice text and/or Bullets and choices shifted right about 20% of the screen width.

Re-applying the master or "Reset Slide" doesn't fix the broken layout. The master looks fine, the question layout doesn't.

Sometimes creating a new question and re-entering the question text will result in the correct layout. (This is a lot of work if all questions are affected)

Has anyone else experienced this? Is there a better way to resolve the issue?
