Yup, as good as Vans is at making parts this kind of mistake is not unique. I had something very similar in one of the J-stiffeners in my empennage that wasn't bent correctly, and mine wasn't the only one. I was building at Synergy and one of the other clients had the exact same issue as me.
Vans was very good about getting the proper parts to us, so I suspect they will do the same for you.
