The rover never disarms itself!

good morning, my autopilot is Pixhawk. I have a problem with my rover. After the firmware update the rover’s engines always remain armed. Before the upgrade I had to both arm / disarm from the radio control and press the safety switch to arm / disarm the motors. this is very dangerous. the parameters seem to be correct. could you give me a hand

can you post up your patienter file, I suspect the parameter your looking for is ARMING_REQUIRE
