Displaying Floor Sheathing

[astrigal]

I am having trouble showing the bottom line of the floor sheathing in section view.
I've turned on all the layers, built the framing for floors and walls and still no bottom line.
I'm not sure where to go from here. (See Picture)

It shows if you take the picture the other way.
But I used a box instead of a line to add a fill,
