Position mode after altitude mode problem with video

Hello everyone.
The device is a hexacopter. It weighs 15 kg.
I am leaving the video and log of the flight below.
On a high wind day, during the altitute mode flight, I switched to position mode.
And when I noticed that there was high oscillation in the device, I switched back to altitude and let it recover. You can notice this at the 30th second. Also, pay attention to the 30th second in the logs section.

What do you think is the reason? Why does the device enter high oscillations while flying in position mode?

You will also notice that the yaw rates are very bad şn log file. I did manual PID because of the autotune problem. It may have failed in YAW.?
