Level control question and the SysEx Data tracks

the automation or whatever it is called, when you slide the sliders of a track in the mixer f3, they are supposed to record and play back? and it was working, but now it’s not - I have both R and W both lit/on. and what are these SysEx Data tracks that get automatically created, I have 4 of them, I keep deleting and they keep appearing.

I noticed the inability to control volume usually is on imported midi files, if I draw a track and play some notes, then the volume changes work
