I can’t really tell because the picture is kinda small, but is that mud or water with no texture?

 

in fact it makes a kind of double soil in addition to the normal soil of the gridmap

 

I don't really get what the OP means, all I see is the orange which is most likely a broken texture.

 

my gridmap is bug because there is a kind of soil without flat texture in addition to the ground not bug that is not flat
