Heading and distance fault - creating a basic flightplan

Brief description of the issue:
Creating a flight by selecting Departure and Arrival - the GPS plan always show more than 5000 nm with wrong heading.
Example: A trip south between MMRZ and MMOB (actual 13 nm) GPS in aircraft reads distance 6731.1 nm - hdg 64.
Aircraft does fly wrong heading - ignoring magenta path.

Carenado Mooney is OK with the Garmin GN530 mod . Placing aircraft on an airport, and create a flightplan from scratch. - But even with mod, the same bug shows with basic fs2020 plan, just as default aircraft

At very first flight - this flight was stuck, unable to pick a new one.
Checking fora - this is a bug related my username containing scandinavian letter Ø.
Ticking off a beta box in Win10 - able to read UAF (?) was a success

Checking fora again for previous report on actual bug - a post suggested a beta box de activation along with reset clock to EN may fix it . I am not sure exactly what he meant… Anyway this was not confirmed to fix thisbug.

Confirmed to be beta box enabled
