Routing out channels with jacks to an analog mixer

Heya guys

I’m having an issue that keep me wanting to pull out my hairs.

My setup is a new MacBook with Sequoia, Logic 11, Steinberg UR816c and my analog mixer.

I simply need to route out 6 mono channels from logic in to my mixer in order for me to make a mix that I then can record again… That’s it.

Before I had installed all the drivers and software, the IOS allowed me to route out 4 channels only.

Now I’m stuck with only being able to route out 2 channels and I can’t seem to solve this issue. Anyone having the same issue or anyone would know what I might have done wrong in my setup?

Some help would be truly appreciated.

Edit: okay, now I have discovered that Logic 11 will default my interface as a soround sound, and That I cannot assign my tracks in the audio settings (but I can do it on the individual tracks in Logic)
