Anyone else run into a bug like this?

JJos2XL mp1k, I got a 2 bar sequence with three tracks. Track 1 vocals, Track 2 drums, Track 3 bass. I'll be **** around with the bass track, and go to Seq Edit or something. And if I got to note 001.03.29 Pad:A4 & change it into 001.03.29 Pad:A5 via jog wheel, when go to the main screen and press play to check it, one of my drum notes will have erased itself or turned a kick into a hat. Once in a while it will do it while I'm in overdubbing live, but it doesn't make any sense, because the drums are part of a different track so there's no way for me to change it unless I'm editing in the drum track.

i also noticed that bug sometimes. if i change a note in STEP EDIT, a random other note in a random other channel is changed (maybe not random, but i dont understand the pattern it behaves).
I also noticed this (sorry for my english, kinda hard to explain for me) - when in STEP EDIT, i hit EDIT, MOVE, and when i changed the value, the UNDO button is lighting up, before i hit DO IT. If that is the case, i know that some note somewhere is already changed.

I have JJos xl 3.47 on MPC 2500

It is supposed to be lit when you do that because essentially you changed the recording. And when you change a pad like I was talking about you need to be careful because you can accidentally change something else. The reason it's acting strange with mine is because the samples that are changing are not even on the same track that I am editing.

but sometimes, it lits immediatly when i change the value even before i hit DO IT, and if that is the case, some note somewhere is changed (in a different track).
it does not behave everytime like that

Undo key lights up to idicate you have overwrite previous "undo", it doesn't have to write anything, entering some windows clears it.

What OS you are on?

I have jjos 3.47

Ok i try to explain it again. Undo button lits up BEFORE i hit do it. Not everytime, but often. It should lit AFTER i press do it, but it already changes when i change value without touching do it. It should lit up after i hit do it, not before!!!

Ifthat is the case, a different note,pad or whatever in a different track is changed.
I am pretty sure its the same bug
