Top Altitude Falsely Reported in DJI Go 4

Just curious why the Go app shows my "Top Altitude" at 582.0 ft when I never went above 397 in all my flight data?

Where is the highest place you've launched from?
That's what Top Altitude is referring to (+/- GPS altitude error).

Flat level Dallas/ Fort Worth Texas. No hills, mountains. Google shows my area 607' above sea level...if that makes a difference.
