Vertical appears tilted in isolated area. Glitch in software?

Elevation should be +/- 20’. Elevations in this area are ranging from -400’ to 500’ I have processed this area around 50 times. The control appears good.

Any help would be appreciated.

Can you attach your PDF quality report so we can understand your project better?

Try using the Accurate Geolocation and Orientation for the calibration method. It should improve your results.
