Why is there a gap in my staircase?

[Anonymous]

Hi, 

I've made a staircase with a sketch but when I look in 3D view there is a gap halfway up the staircase as shown in the picture. 

The drawing for the staircase seems to be fine though. 

Does anyone know why this is happening. Thanks.

Revit doesn't seem to like the risers ... try to tweak the angle of the last couple of risers before the straight run....Riser #10 and #11

Try increasing your structural depth.

Here is the file for the stairs.
