Now I know why it is happening and how to fix it:
"Insert an extra edge"
But this just makes me wonder. Is this really the proper way to do this? Is there not an easier way? I tried thing like editing the tangents or splitting the surface around it's edges. But these methods did not give proper results. (I might have done this wrong?)
The problem that I have with the extra loop is that I have to reweld the verts and that I thereby lose the original position of the vert. I can put the looped vert on the same position of the original vert using the edge constraint. But that doesn't work in each situation.
