Hello,
This is a big bug indeed!
I just tested with my MPC Live 2.4 and I can confirmed this unintended behaviour.
Maybe it is related to another bug: q-link display always show track numbers associated with pad bank selection of the main mode. If you play with the C bank in main mode, go to track mute mode, hold the q-link button and it shows tracks 33-48 (though q-links actually control tracks 1-16, which is intended) regardless of the selection of track mute banks.
Anyway, I just sent two messages with the "report a bug" feature via the MPC software.
You can send your bug too, and to be sure it will be reported (it is an important one), I suggest you to make a post on Gearslutz with the link of your video. Dan from Akai (alias "xparis001") quickly answers to this kind of problems:
