Flight plan invisible

[Red Dog]

When I create a mission (Marianas) in Stable version, There is no way i can see my flightplan.
Steerpoints and lines remain invisible although there are placed on the map as I see the steerpoint number incremented and when I enter 3D I see the flight plan in my MFD. So I know they were created - they are just not displayed on the ME map

 

If I do the exact same procedure with the latest beta version, I perfectly see my flight plan in the mission editor. They are created fine, and I can see them on the ME map

 

This was tested with Marianas, F-16 stable and latest beta.

Any idea if that's me doing something wrong, a known issue or something else?

 

5I clearly made sure the hidden on map option was NOT checked obviously

Thanks
