Fence upload error

Mission planner 1.3.74 latest stable version and arducopter 4.0.7 trying to upload fence via data radio connect I couldn’t upload it says error.

Where as same via trying to upload via USB Direct connection with cube uploading …

How could solve this?

check that the serial port for the radio is set to Mavlink 2

Yes its serial port as Mavlink 1 only. I will check with Mavlink2 set .

Difference between them?

Mavlink 2 includes extra functionality for fences and numerous other things

Thank you
