Just downloaded the 3.2.1 demo and was setting up my template. Noticed there's a small glitch when you try to hide the last track of a multi-output instance. It ends up hiding the first AND last track.
Here I try to hide the track:

And the first instrument track also is muted along with the disappearance of the last track.

Not sure if people have this glitch before. It only happens with the last instrument track as I've tried it in other tracks.
