Clipping Plane Bug

For a pretty long time I had this bug in my rhino which is really troubling. When I apply clipping plane to a model and activate the perspective or any other view for clipping plane, the cut doesn’t “cut off” the object, there is always extension of the object from the plane cut, so I can’t get a clean view of a cut. I tried to redownload the rhino but still the problem appears. I wonder how can I fix this problem.
