I updated to APM3.1 last night and went through the whole setup process. But i noticed in Mission Planner, APM Planner 2, and Droid planner all of my flight modes show up as "Unknown".
It appears to be switching into correct modes by the sound of the motors (no rotors) when i put it in loiter and move it around vs put it in stabilize.
I can grab some logs tonight if that would help anything. Or is this a known issue? I didnt find anything off google regarding it.
