Manually tuning PID's, using autotune logs - values are automatically not saved

I’m new to log world and would like to know if there is some logical explanation in autotune logs to use this info to manually tune PID’s. I’m trying to do this because autotune won’t save my autotuned pid’s after disarming. It may be caused because my aircraft somehow disarms itself when landed in althold mode.
I’ll also post my binary log file where I tried to autotune my 7kg aircraft. But as said before- values are not saved.
