Pan Issue

I seem to have lost my pan control. I probably hit something since I am new to 15. I have a mono track bussed to a stereo sub group, which is being sent to the main stereo bus. The track pan control seems to be acting like a level control when I am hard right the level is zero and gets louder as I pan left. Yet I see the pan levels on the bus and main moving properly. But I just get a mono signal. Any thoughts would be aptreciated. Thank you.:upside_down_face:

It was me the USB interface was set wrong. Thanks anyway.:grinning_face_with_smiling_eyes:
