Error during Auto landing

The phenomenon of taking off again as soon as it touches the ground upon automatic landing

How can I solve this problem?

DISARM_DELAY, 0 (or greater than the time before take off again)

MIS_OPTIONS, There is Only description 0 or 2 options in the ardupilot docu and Mission planner parameter.

Should I ignore it and change it to 4?

The common error of not understanding it’s a bitmask. Many parameters are. This one states that it is.

Thanks, I should test again in this week.
