Undesired flight mode change

I was using PX4 in OFFBOARD mode for autonomous missions with a companion computer. After the triggering of LAND mode in last flight, the controller passed to STABILIZED mode immediately. This was undesirable mode change for me. As you can see in the RC Input, flight mode wasn’t changed, but you can see some RC noise on thrust, pitch and yaw inputs that can be a reason of this but RC wasn’t being used by the time. The companion computer never sends a command to change the flight mode to STABILIZED. I couldn’t see any suspicious thing on the logs. I couldn’t figure out what is caused to change of flight mode. I am using 1.10.1 for a long time with companion computer and this is the first time, I have met with this kind of issue.

Thanks for your help,
