This file is incorrectly tagged at a variety of levels, but I don't see anything that should cause "instability" per se.

Tagging problems include:

1. Incorrect usage of List tags
2. Incorrect usage of Heading tags
3. Rule-lines should be artifacts (right now they have alt. text reading "---".

On the other hand, all the tags are, at least, in the right order.

It's possible that the list tags are screwing things up - certainly, they will confuse the heck out of a screen-reader.

Suggestion: Remove the list tags (ie, convert to Paragraph tags) and see if the problem remains. This would be best accomplished by redesigning the Word file to remove the unnecessary enumeration, then re-creating the PDF.
