I have that problem with my 2011 A128. The upper door's edge molding rubs against the ceiling when the camper is folded down, wearing an arc-shaped "scar" through the paint up there. It's unsightly but isn't damaging the ceiling otherwise. Took me a while to figure out where it was coming from. I now put a piece of cloth over that corner of the door just as the roof is closing. I suppose I could adjust the roof latches to not pull the roof down so tight, but that might keep the gaskets from sealing around the roof edges to keep out rain and road spray while traveling. As they're adjusted now, I have no leaks while traveling in storms so I just live with it, but if there's a cure I'll be glad to try it.
It's never too late to have a happy childhood!
