Hmmmm there were no airports in that area.
None at all .... except for the one that was one mile to the west of your position.
And that's the one that the app was warning you about.

I think you are on to something here, obviously because of the NFZ warnings received. However, I'm seeing disconnects between DJI's geo fence data and the FAA sectional for that area. That airport at most is a Class E airspace field, which requires, per FAA drone regs, that all flights be outside 5 mile radius unless defined otherwise, in this case it applies. More likely it is a Class G field but the 5 mile rule still applies. This means that the OP at a minimum would have to obtain tower or airfield manager approval, since in this case it is an uncontrolled field (no control tower) he would likely have to coordinate with the field manager, whomever that is. In part, technically it requires FAA authorization first then airspace coordination which may have to be the local RAPCON, many of the 107 folks differ on just which and what is actually required, as the FAA is still sorting out just how that process is supposed to work. Also, it greatly depends on whether he is flying under 107 or 101 rules, my guess its 101. For now airfields like this are more in the wild west category.
Now with the FAA techno stuff out of the way, the geo fence data shows a yellow circle that is only indicating a 1.5 mile radius, not that I'm complaining about that I am not, but it does not synch with the FAA rule set. However, the more curious problem I see is that the OP was taking off and operating within the circle, by as much as a half of a mile per your own calculation. Clearly, the OP stated he unlocked this zone, and he must have as he was able to operate in there, would he not? Either that or he just thought he did but actually didn't. Since DJI does a poor job of actually stating the differences in their defined zones and what those zones are supposed to represent i.e. red is Class B, C, D airspace and yellow is Class E & G I think; even that is a problem as drones can operate in class G airspace with restrictions as noted above. DJI definition: Authorization Zones. In these Zones, which appear yellow in the DJI GO map, users will be prompted with a warning and flight is limited by default. Authorization Zones may be unlocked by authorized users using a DJI verified account.
So, my point is, would he have been able to takeoff in an authorization zone without unlocking it?
If so, then what does limited mean?
If not, then he must have successfully unlocked the zone, so then why get a warning at about 1 mile distance when the circle goes out to 1.5 miles?
Worse why would the bird be acting like it was hitting the wall at 1 mile, especially if it was unlocked?
Now again, I think you have a point here and may be correct, however, something is not adding up.
