I have two lofted surfaces (option loose). The upper surface with the green loft curve is resulting in a surface that can not be splitted by the cutting plane. The lower surface with the cyan loft curve is resulting in a surface that can be splitted. I can not find out what is wrong with the green problem curve. Can you help me?
See attached rhino file.
