I have a door that I have been designing in SW and just got to a face where I need to add another flange but cannot select one of the edges to add it. It is very strange, I have changed the flange, deleted it and recreated it, restarted SW, nothing changes it. I attached the part and added a note to detail the edge I am talking about. If anyone has an idea of what I did wrong here but I think it is a genuine bug.
