do you have the narmour be gone fix? if not, it's probably the skirt hinge mesh.

Chassis must be a bit taller.
Yeah, at that point I presumed the chassis sloped down.
there is a chassis wedge thus you cant put the sheet all the way in the front because theres a minimum chassis height that you can put a halfsheet on
If you put the half sheet back far enough, then you can use a 40cm metal sheet, attached to the end of the half sheet, to cover the remaining area.
