Mono Preset in Control Room not playing Right Side

Anybody heard of this? I have discovered that when I select the Mono Preset in Control Room, it is only playing the channels that are panned to the Left. Stereo Preset is playing fine.

Anybody know a fix to this?

Configure your settings and devices correctly…

I’m sorry-were you trying to be funny?

Clearly something is incorrect, and clearly I don’t know how to make it correct, otherwise I wouldn’t be going to the forum for help.

Is there anyone else out there without a smugness to them that might be able to help someone in need? I’m sorry, but I have some important things to attend to here and this has become a tense situation in my studio and I don’t have time for Trolls. Just honest, unjudgemental help.

Thank you to all who might be able to provide that.
