I suspect it only updates the gpxset.ini once each PF is used - because that's what multi does to the names too, ie the 'new' names aren't shown in the game driver selection screen until the PF has been used, then they do show after that (and next time).
Maybe try again and just briefly load track 2 and track 3, then check gpxset.ini. I think you'll find it will populate as expected.
Alternatively, you could just stick this in your gpxset.ini:
[PerfManager]
Enable=1
Path=gpxpdata\Performance\00.txt
Path01=gpxpdata\Performance\01.txt
Path02=gpxpdata\Performance\02.txt
Path03=gpxpdata\Performance\03.txt
Path04=gpxpdata\Performance\04.txt
Path05=gpxpdata\Performance\05.txt
Path06=gpxpdata\Performance\06.txt
Path07=gpxpdata\Performance\07.txt
Path08=gpxpdata\Performance\08.txt
Path09=gpxpdata\Performance\09.txt
Path10=gpxpdata\Performance\10.txt
Path11=gpxpdata\Performance\11.txt
Path12=gpxpdata\Performance\12.txt
Path13=gpxpdata\Performance\13.txt
Path14=gpxpdata\Performance\14.txt
Path15=gpxpdata\Performance\15.txt
Path16=gpxpdata\Performance\16.txt
Path17=gpxpdata\Performance\17.txt
Thus getting everything done in one go!
Notice that I don't use the track names in my PFs. It doesn't matter what names you use, but I find it less confusing. Also, if I decide to change the track, the PF still works because it refers to the slot, not the track, because in some mods I like to have two track sets to choose from.
PS: You can also copy gpxset.ini across from mod to mod too, which is easier than using the Multi button 17 times!
