David, I may be missing something here.
Can you not find the CD/album miss assigned in under "Various". In the right-hand side window under "Various", double click on the offending album and a Rename album and artist box should open up. This should allow you to change the artist from "Various" to "Dolly Parton" and save it. Name to whatever the first 2 CDs were called.
Sorry if I'm totally off the mark here, but hopefully this helps.
