It seems the surface type 2.75_Exposed floor doesn't work properly

Hello, I’m trying to make an energy simulation for a building elevated over the ground, so the floor is exposed. I’m making the zone using “createHBSrfs” component one by one and for the floor, I’ve chosen surface type “2.75 - exposed floor”. The zone seems to be created properly, but when I use the “LabelSurfaces” component to check the wind and sun exposure it shows “NoSun” and “NoWind” for the floor. What am I doing wrong?
