Virtual DJ - Cue Button Problem

Trying to use my MCX8000 with VDJ , have configured it as per manual but Cue button on channel 1 does not mute when pressed to do so , channel 2 is ok . Any ideas ?

Cue buttons don’t normally mute

I guess he(she) is saying when he turns the cue button off it still plays music.

If You have Your headphones control section set to listen to MASTER and CUE at the same time, and You press CUE on the channel that is having the fader UP (is sent to MASTER), then even wen switching CUE OFF will still let You hear the track. CUE buttons don’t mute, they rout the signal to Headphone section or not.
