More details: What's happening is that *every* album is being listed under *every* top level group. Within each top-level group, the albums are correctly being grouped by the second-level grouping, but they are not being restricted to those that match the top-level grouping.
Example: supposed I have two albums in my database, of different genres and different artists, and that my groupings are by Genre and then by Artist Sort. Then I should get
Genre 1
Artist 1
Title 1
Genre 2
Artist 2
Title 2
but I'm getting
Genre 1
Artist 1
Title 1
Artist 2
Title 2
Genre 2
Artist 1
Title 1
Artist 2
Title 2
