Track levels and voice not working properly

Hey guys, so I just got a new digitone and I’ve been having some trouble with it.
Mainly, the track levels seem to change globally, affecting all of the track instead of the one I’m working on and for some reason the sound on one of my tracks doesn’t seem to change even if I erase it or mute it.
And that’s about it, any help would be greatly appreciated.
Thanks!

Edit: Sorry for not replying, solved it, seemed to be a problem with the voices. Heh.

Try to run a test mode to see if there is any problem , while powering up press and hold func key , then press trig 1 to run the test
