I am trying to do a cut through an edge flange on a sheetmetal piece.  I unfold my bend and sketch the cut, the cut works great and then I try to fold the bend and it comes up with an error that says "This bend has a beveled cut which cannot be handled" I cannot figure out why it is giving me this error.  I have tried numerous ways to try and resolve the problem to no avail. Any help would be greatly appreciated. I am very much a novice to the sheetmetal tools but I have had no problems with most of it.  I can just put the holes and it will bend just fine, but when I add the slot all the way through the flange it gives me this error.
