Fence not able to write via RFD, but no issue writing via USB.

I recently ran into an issue where the fence would not write to the aircraft on 4.4.4 when connected via telemetry through RFD. I tried both Mavlink 1/2. When connecting with the USB cable the fence would write to the aircraft with no issue. Anyone have any ideas what might be causing this?

Had no issues writing to 4.4.1 via RFD 900 though.
