I know all about how to correctly select the left and right multiplex in edit.

What I tried to point out in my message is when there is a LEFT MUX song and the VOCAL button is clicked to activate the vocal, the VOCAL button changes to NO VOCAL, but the vocal doesn't play. At this time the vocal should be playing. When the NO VOCAL button is then clicked it goes back to VOCAL and the left vocal will then play. To turn off the left vocal, the VOCAL has to be pushed again.
