M8N Compass Not Shown in Compass List

Hello All. For our capstone project, we are building a drone which will use Arducopter as the control software. We are using a Holybro Pixhawk 6Cflight controller and a Holybro M8N GPS module. Unfortunately, I am not seeing the external compass in the M8N GPS in my list of compasses. The only one listed is the internal one in the Pixhawk 6C controller. The GPS in communicating and I cam getting position info so the communication between the two devices appears to be working fine.

I am running V4.3.7.

Any Help is appreciated!
