Apparently I will have to chalk this up to ghosts. I exported out every field in the PR1 file and NOTHING was any different from any other employee. They only have about 8 employees, so it wasn't hard to see them all at once.
I hate giving up, but since I've been on my own time the past half hour of investigating anyway (since the client is OK with just doing it manually), I guess I'll have to hang it up on this one.
Dang.
