Thank you for being so helpful, but I figured it out!!!!

In my section headers, I had "link to previous section" checked. By unchecking it, I was able to simply put in the right ones and Word did not monkey with them (it was doing it when it saved, apparently).

Here's the link to the page that helped me, in case anyone else runs into this type of problem:
