Edge after revolve?

There is an edge on the shade after I revolve it. How do I remove/hide it?

I suspect that you've got two control points on your spline that are too close to each other. This will create artifacts like unwanted edges. Right click on your sketch, select edit sketch, and zoom into the area where you see the edge. You may need to move or delete points on the spline. The 3D form will update automatically.

I have the same problem and moving and deleting points on spline is not helping.
