Do you have sloped topography? The parking stalls get buried in the slope, as they cannot "bend".
This is a long-standing known issue, which has never been fixed.
Check if the stripes show up in a 3D view.
So do they have any plan on fixing this.
Workaround is to show my site plan in wireframe or scrap the topo part of Revit and draw everything in 2D.
