Maybe I'm misunderstanding your response, but one thing I should clarify is that there's already a page with all of the proper row heights. What I was trying to do was expand on this in the same document with a number of additional pages, all set up the same as the first. I'm basically copying the row heights from that page, but they're not sticking.

Is it possible that it could be a font issue? Ergo, the font sizes for the rows in the first page, which I'm working off of, are all set correctly, but then in subsequent rows I haven't adjusted, and thus they readjust after I set them?
