Newly created spline is invisible

[quickytools]

I create a new spine in the editor but the spline doesn't show. Control points exists under the curvy spline object but the spline is invisible. If I toggle tangents in the View options the tangents show. The control points and the spline do not.

If I open any of the example scenes with splines those splines show in the editor. When I create a new spline in these scenes the new splines are invisible. Why?
