Sketched bend not acting like it should

I'm bussy making a part of sheet metal, but it has a weird error.

Every time i try to unsuppress a suppressed extruded cut, it just stops working. I have included the file to give a more clear view of what's going on, because i don't get it at this point.

KSR,SR and KST are one side, other side are the T and ORU. once u unsuppress one of them u will get an error when trying to suppress it again.
