HDZero stuck on lowband

I just made my first build with the HdZero Race V3 VTX and the Runcam Nano 90. The VTX is set to Raceband 1 on betaflight however I have absolutely horrible video range and can't get very far. When I entered the VTX menu on my osd it told me that the VTX was actually set to Lowband 1. Whenever I tried to change this to raceband 1 (or any other channel) even after pressing save it would stay stuck on lowband 1. When I entered lowband 1 on the goggles, I could not see any video. Any help troubleshooting would be amazing.
