2d edit on draw parts

Hey there,

I've been having trouble with 2D editing when trying to modify a cut-out in a draw part. I can still 2D edit cutouts in cabinet parts, but not in the back or bottom of a Blum Legrabox. Is this because they are part of a subassembly or something? It used to work perfectly fine, but now it suddenly doesn't.

Anyone have any ideas?
