Aircraft 4.1.7 the engine does not turn off when the parachute is turned on.

Hello. I am making an airplane project, using the Durandal flight controller firmware 4.1.7 the engine is configured for Dshot 1200. When checking the parachute, the servo is triggered, but the main engine does not turn off. How can this be fixed? And more. In firmware 4.1.7, when setting the AUTO flight mode, RTL is turned on. I think that in both cases, the reason is an incomplete firmware.

Post a log (.bin) and we can try to help. Sounds like a configuration issue to me.
