Auto mode not follow waypoints

ArduPlane Plane 3.9
1

Hi to all,

I have a problem about navigation in Auto Mode of my QPlane.
I don’t understand why it turn here:

As you can see in the LOG 2 file I have done the tuning of NavL1, Damping and Xtrack.

Here are all the log files

There is another question, what is the difference between NavBrg and TBrg.
