No Sound trough HP Outputs on UAD Arrow

Hey there,

I'm on a Mac mini M1 running MacOS Ventura 13.5. I tried using the reference app for my Headphones and my monitors but the app for some reason does not output any sound when I choose my HP L and HP R output from my interface. Choosing the MON L and MON R outputs works fine, but it then changes the signal for my monitors AND my headphones. Is there a way to use two different sound profiles for monitor and headphones on the UAD Arrow?
