Cannot change output settings

Hey team, all of a sudden I cannot change output settings on my machine. I recently added a mixer to my setup and now am running multi outs. Which was working fine last session. Today I loaded a blank project and in the track settings the output of all pads are locked to mono. Clicking on it with the select knob doesn’t do anything. Have reset many times. Same issue. Also, I saved a project as a template with my multi outs last session. it also is has all tracks now set to mono.

I’m going to reinstall the latest driver see if that does anything.

Any ideas?

so I just worked out, you need to have a sample loaded before you can change the output settings.

Is there anyway to save a template or do I need to adjust these settings once I input my samples every time?

Thanks
