ITunes keeps old artist names that are incorrect, even after remaking the database

Question

I have a huge classical music collection. Using iTunes is a frustrating experience since the tags are quite useless. No one wants to search for
this conductor with that orchestra
as the artist. You want the composer!
And then, in multiwork sets, iTunes tags a CD as
Beethoven symphonies - Vol. 2
rather than
Beethoven: Symphonies Nos. 3, 4
And, for example, I am reripping Dvorak's works. As I type in the Artist (composer), the first choice is
Dvorak, Anton
Then it lists the correct
Dvorak, Antonin
Where is it getting the incorrect name from?
I once had Anton by accident, but I retagged all my files to make this correct. Now iTunes does not list Dvorak, Anton as an Artist, but it is still there when I retag.
I deleted the .xml and .itl files in my music folder, and remade the database from scratch. They are still there.
How do I fix this?
