G3000: Can not add routes (airways and waypoints) to flight plan

[HeliSteveNZ]

While at some airports I can not load airways and waypoints on the flight plan. For example, When at KEWR (Newark) I can load the departure and then select the airways and exit waypoint, however, it would not load on the G3000. However, if I am situated at NZAA (Auckland), my home airport, I can load an entire flight plan from Auckland to anywhere, and I can load the entire flight plan I tried from KEWR without an issue. Why?
I have everything removed from the Community folder except the Working Title G3000 mod and Navigraph.
This happens on both v0.7.6 and v0.7.7.
The latest update of FS2020 is running.
