That is actually a bug. This is a waypoint bug. I think if you go to Flight Plan and clear all, then continue. You will see it go away.
Basically is it auto assigning a waypoint or departure to the nearest airport (8N7). If you touch Flight Plan, you'll notice a Departure is assigned to your location or a nearby airport if within a few miles of one. Just "clear all" unless you plan to add additional waypoints.
This should be resolved in 7.0.8B
