Part won't stay flat

Why do some sheet metal parts stay flat in a drawing and others don't?

If I leave the part flat when I save it it will appear flat in the drawing where it's supposed to but if I leave it folded it will appear folded in the drawing where it's supposed to be flat.

Doesn't effect the first page where the part appears folded.
