I was playing around with the holodeck and the fade it. It seems to spawn to low down. I have to move the Y axis to about 4.0 to make it look right.
It might be to do with the map but it just seems it is set too low.
Were you using it on a ground map? The ground on a ground map seems to be elevated, whereas the floor on an interior is set at 0. So, it's likely that if you use the effect on an exterior ground, you have to elevate the y.
