Hi Claus, an edge like that is normal to have with a closed surface, it's called the "seam edge" of the surface. It's just part of how NURBS surface geometry works. A NURBS surface is internally structured as a 4 sided patch. To form a closed surface like a cylinder out of a 4 sided thing, you need to roll it up so that opposite sides are touching each other. That spot where the opposite sides meet is that seam edge. A NURBS sphere made from one surface is similar, it also has a seam edge but additionally has the top and bottom edges pinched down to a single point.
It's just something to get used to I guess, it's normal to have it on a closed surface and it won't have any negative effect on 3D printing.

... or 3D rendering! ;)
