See previous issue, track number labels and track numbers in Range Selection do not match.
In addition, there is a serious bug related to the same: select a midi part on one of the mis-numbered tracks and open List Editor: it opens with the data from a DIFFERENT track, the one 3 lower where the mismatched tracks are off by 3.
I think this is what caused me and perhaps many other new users to have so much trouble with getting to know the program — selections were so unpredictable one never knew whether it was user error or programming error.
This one needs to be fixed!!!
