Just upgraded and have been setting things up the way I want them and come across a slight problem with the control room. I have setup my main monitor outputs (1 2) and then another output to my headphones (11 12) - screen shot attached. However, when I switch to the headphone output in the control room I get it out of both my main monitors and the headphones.
Not sure what I am doing wrong but quite sure this is how I set it up in Cubase 10.5. If it helps I am using an RME Fireface UFXII as my audio interface.
