In my experience, this happens when you have the plane created as a feature
in an assembly, not in a part, and yes, sometimes no matter you have the
visibility turned off on your assembly, the plane/axis will appear on
further assemblies where you use it. Honestly, at present date I haven't
found the solution for that and I would like to have it.

Such is life.
