soil problem view in plant

[nicnoc]

Hello, everyone. I have a problem with the display of the soil.
in section you can see well with the retino that I assigned to him, while in the views in plant of the basement rooms nothing.
I checked graphics visibility, okay, soil layer thickness, okay.

ah I forgot, in substance I have more semi-interred levels, from one floor to the next the plant "to widen", under I realized a platform to cut the ground, can it be for what I do not see anything?

As soon as I can... Basically, I have a building that is partly buried. the land passes from zero to +660. I also have basement rooms, up to -900. You can't see in any plant buried the ground.
