ptPanel3DCustom does not close the curve


I created a surface using a sweep with two rails, and an ellipse as a curve. I’m trying to panel an object in that surface so I used an offset of the points (previously divided the curve) and the problem is that the curve does not close when using the Panel#dCustom command. See the picture.

It does not close in the end nor along the ellipse.
