Hello,

This is the first time I am working with Sheet Metal. I created this part:

But when I try to flatten it, I get this:

As you can see, the big semi-circles are gone. I cannot figure out why. The bends seem quite logical to me, I don't see why this shape shouldn't unfold properly. It seems that SOLIDWORKS doesn't like that little bend at the left. Can someone please point out my mistake? I am attaching the model file.
