I have a mirrored sheet metal part:

displaying correctly in the "bent" view.

Viewing the flat pattern shows something completely wrong:

The parent part, flattened out, looks like this, the correct way:

The part was created using a lofted bend, I've had this issue a few times before, always with mirrored sheet metal parts using lofted bends.  Sheet metal properties are identical between both parts, the only way I've found to fix this problem, is deleting the mirrored part and creating a new mirror.  Any help would be greatly appreciated!
