Mav air altitude way off

[Spawn840]

I have two mav airs and both have the same issue . They either say there higher or lower that they are. Like it says it's at -4 ft an IRS 12 ft above the ground . Or it will say it 20 ft and it might be 3. I have seen it say it was at 1120 ft an only be maybe 100. As well.

Is this directly at the home point or some distance away? If some distance away have you flown out over any declines / inclines?

All in the same flight in a 250 yard area no big changes on ground . The ground is flat. Its strange it's not every flight. But it is most. The two areas I fly one is home alpharetta GA the other is the Chateau Elan area . All flights are for the most part line of sight as well. My spark ,phantom 3 an inspire 1 do not have this issuse..
