the spline drawing tool created 3d inlcude geometry.
good luck finding and selecting those when everything overlaps and the UI states 3 times sketch point without telling who owns wich point.

so I need to delete the constraints move the spline then delete the 3d include geometry
and then I can move the spline back ...

pretty inefficient workaround - a with simple show and hide or better geometry selections this would be a one click deal.
