Cannot take off from a water runway with selected aircraft

Hello everyone, So i’m new to
this SDK program (3 days) and now I’m trying to convert my hometown airport
from p3d to msfs using MCX, so the point is when i’m finish the airport and
try to test it, i can’t enter the runway with the normal airplane, and i just
suddenly notice in the world map that my airport symbol change to the anchor
symbol which means it’s detected as a water airport/has a water runway not the
normal one as it should be, I’ve been check everything and i don’t know what
to change to make it a normal airport again, any help would be appreciated,
thank you.

You need to make sure that your runway has a material assigned Then, if needed
, you can make it transparent

Hii!! I try to add the material
to the runway but it seems the problem is still in there when i going back to
the world map the anchor symbol is still there…

Did you build your scene/placed it in community?
