Hello, I flew with the Phantom 4 RTK with terrain awareness mode.I had planned to fly with terrain awareness mode at 110 meters altitude.It did this on the first battery. But when I sent the second battery to continue again, it rose about 125 m more.Drone followed the terrain from a height of 225 meters.
This is not reliable at all.what could be the reason for this

I've heard that there are barometer errors. Having trouble with the same problem
