Why is the jazz genius mix titled "Classical Mix"?

Question

I'm running iTunes 10.7.0.21 and everything seems fine. The only strange thing is that I have two Genius mixes, each titled "Classical Mix." One of these consists of obviously classical music from my music library, but the other consists obviously of jazz. There is no Genius mix called "Jazz Mix," so it looks like the jazz mix has somehow gotten titled "Classical Mix." I also have other mixes (Alt. Singer/Songwriter Mix, Indie Rock Mix, Chamber Pop Mix, etc.), but it's really strange that a mix that consists of Billie Holliday, John Coltrane, Ella Fitzgerald, Shirley Horn, Miles Davis, etc. has a label of "Classical Mix." Meanwhile, the second "real" Classical Mix has Bach, Beethoven, Vivaldi, etc. This is really strange.
Is there any way to retitle my Genius Mixes?  Is this a bug?  I look at my music by genre and I clearly have 120 albums that are labeled as "Jazz," so why does iTunes insist on calling this music a "Classical Mix"?
I've tried turning off Genius and turning it back on, but that does nothing. I've figured out which "Classical Mix" is really the jazz mix, so this is really a minor annoyance, but why doesn't this work correctly?
Thanks.

The latter.  I just recorded a bass track as an audio track along with tracks for guitar, banjo, harmonica, etc.  (I bounce off line so playing along with the bounce is not possible.)  The thing is that the other instruments I play are all acoustic, so they go on their tracks through a mic. The bass is an electric bass guitar, and while I have an amp and could mic it, it just seemed easier to put it on a track by plugging it right into the preamp, which has an "instrument" input setting as an alternative to the "microphone" input setting. 
What is so screwy about this is that the normalize function in the bounce window should make proportionate adjustments to all instruments.  At least that's what the owner's manual says it does.  But what it seemed to be doing is treating the directly input bass and the microphoned instruments seperately.  I usually record the bass track at a fairly high input so that I can clearly hear it in the headphones as I play over the previously recorded instruments and vocals.  Then I rely on the mixer to bring down the volume of the bass to a more reasonable level in the final mix.  But with the normalize function on in the bounce, the bass was still coming through in the bounce at the original input level or something very close to it.  That would be fine if the other instruments were properly jacked up as well so that the bounce sound like what I heard through the mixing board, only louder. But what I got was a mix with all of the all the other miced instruments sounding just like they did through the mixing board and the bass blasting away at the original recorded level notfwithstanding the volume reduction on the mixing board.  Very strange.  I assume this is a software bug, but now at least I have a reasonable work around.  Thanks again.
