Am i an idiot?

Frank, done and phones volume now controls. Dont know what I did but I am now getting sound out the phones. But I am also getting it out the speakers at the same time.

On most mixers when you have the speakers being fed from the control room outputs and you plug a set of headphones into the headphone out jack, it automatically mutes the control room output to the speakers. You may have to call tech support at behringer and ask them if this mixer is supposed to do that.
