The Grand Three Won't Stop Sounding

In Cubase Pro 11 , The Grand Three (5) sounds whenever the master keyboard is played. Because of this, it can no longer be used.

The Grand Three should only be heard “live” when it’s monitor selector is on “input.” Now, even though The Grand Three track is recorded, the instrument is heard at all times whether the monitor switch is on playback or input.

Does the troubled The Grand Three (5) 3.2.0 fix this problem I wonder? 3.2.0 seems to have many new problems added . . .

I’ve had to quit using this instrument.
