Changing track affects randomly some other track?

I was just having a jam, At one point, my bass track suddenly jumped really loud even though i wasn’t touching it, i unmuted some other tracks at that point. No compression applied and bass track is routed to individual out… Also sometimes i’ve noticed the opposite happen, it goes quieter when changing some other track filter for example??? what’s going on? anyone else had anything like this happen? OS is 1.46_beta
