I am using FlyDemon version 3.16.12 on a macbook air.

When defining a new route, it seems that there are MSA (minimum safe altitude) "imposed" for each leg (I interpret this by the fact that the leg in the 'radar' window at the bottom of the screen is depicted in red instead of magenta). 

I find these MSA very high, and they do not correspond to the surrounding terrain altitudes. 

Thanks
