Understanding sound locks

Whenever I try to hold a trig down and turn the track knob, I get a list of ALL sounds in the sound pool irrespective of the type of machine the sound is designed for. The manual says at least that if a certain sound is incompatible with that particular machine it will have a (!) icon next to it. I don’t see that anywhere. therefore its like shooting in the dark. some times the sound lock works and other times it doesn’t and I don’t know which sounds to choose when sound locking.

what is the solution?

might be a bug, but the (!)s are blinking next to the sound names on my MK1

Yeah no indicator next to the name. Mk2 here. Seems like a bug.
