When i pan a mono channel to the right the signal goes away, and when in center or all the way to the left it come out both sides. Am i missing a setting?
Sounds weird!
Confirm what source is selected for the headphones output - check it isn’t allocated to maybe a mono channel of a stereo mix rather than LR?
Apologies if I’m jumping to conclusions, but one way I can think of this happening is if you had headphones connected directly to outputs 1, 3 or 5 on the 18T or 12T and have the output stereo linked.
If this is how you’ve connected up - note that TRS outputs 1-6 are balanced mono outputs and cannot be used to feed headphones directly.
For stereo operation you need to connect to 1&2, 3&4 or 5&6 to get left and right signals and feeding an external headphone amp or IEM system.
If using an external headphone amp which can take a balanced mono signal to feed L&R of the headphones, you should only be using the output in mono.

Thanks. Turns out it was my headphones. I tried another pair and it works properly.
