They aren't based on each other. Somehow, when I pasted the one document, it overwrote a couple of the other styles. So I guess that's what happened. It was only about 12 pages of actual text, so I just went back to a version before I put it in and pasted chunks of text as plain text and made new styles so I could do my TOC. It worked. Once I figured out what had happened, I just figured out the work-around.
