Slot not cutting "normal" in Sheetmetal

Anyone else having this issue? It's been an ongoing issue for a few years now with SW. Anytime I try and cut a slot through more then one face, though a bend, the cut does not stay normal to the faces. I've attached a part to show what I'm talking about. The first two cuts behave as they are supposed to. The third cut is the problem. As you can see, the cut doesn't stay "normal" to the faces. Oddly, if you add any other geometry to the sketch, it will work fine. Edit the sketch of the third cut. I have another circle in there. Change the circle so that it is no longer "construction" geometry. You'll see that the slot now cuts fine. I've yet to see any progress from SW, only work arounds. I would think other people have had this issue...
