Cue sends

I’m having a couple of issues with my cue sends.

First they keep turning off, going grey.

2nd, when I monitor the metronome for any of the four monitor mixes i hear a combination of the click from the main room and the kick level that I’ve added to the monitor mix. This added volume does not go out to the headphones but it’s hard to hear an accurate level going to the phones when i am hearing a combination of the two signals.

Any input on either of these issue would be appreciated.
