Yeah, OP’s photo is missing that triangle plastic piece in the back corner, making it a fake image. Without that plastic bit, with the window filling up the whole door frame, it cannot possibly roll down. It simply cannot fit into the door frame (OP’s image can’t I mean).
Edit: Also, OP’s image doesn’t even have a window frame.
Seems ok to me:

OP’s picture is cropped with a gray background.
