Why do some waypoints appear in the wrong position on HI-TACAN approaches?

HI-TACAN approaches work a bit differently in terms of geo-referencing.  Only the area inside the solid ring is drawn to scale and has accurate geo-referencing.  Items identified along the dashed ring are called enroute facilities and are not scaled in terms of their location.  Occasionally, there may even be another dashed ring with intermediate enroute fixes that are outside of the scaled area.

Also, the runways are not drawn to scale on these plates. Only the approach end of the intended runway is shown in the proper location, the rest are expanded to show relative position.
