Kakute F4 mini v2 m5 pwm output not working

Hi, I am using kakute f4 mini v2 and trying to use m5 pin which mentioned that used for led pins. I changed servo5_function 120 → 1 to send rc_override command and control servo. I can achieve everything with m1-m4 pins but m5 pin does not work somehow.

Also I realised that 5v out which next to m5 pin also does not work. I had a chance to try it on 2th and 3rd f4 mini but they also did not worked. So I guess this is a problem with ardupilot.

I saw this on official documentation of f4 mini v2:
Type in the following command in the CLI window:
resource MOTOR 5 B06
resource MOTOR 6 B07
timer B06 AF2
timer B07 AF2
dma pin B06 0
dma pin B07 0
save
which also mentioned before but not answered in here.

I also need to add that when i change servo5_function to 1, I can see pwm value changes on rc_override on servo5_raw message but it does not move servo.
