4.2.2 upgrade can't select frame type

Hi. I have a Pixhawk 2.4.8 and upgraded to 4.2.2 Rover and the “Frame” section of GroundControl is red because frame is undefined. When I try and select Rover, it is grayed out. It says disabled while the vehicle is armed but it is not. Can anyone point me in the right direction?

NM, I figured it out.
