I have never seen a GPS or Autopilot make the decision "The flight plan system is screwed up...it's unreliable." and then set a course at right angles to the displayed waypoint.    The GPS/Autopilot displays the next waypoint correctly - that is ALL it does on any particular leg.  The GPS does not anticipate the next leg down the road and then say to itself "nope that can't be right - so let's go somewhere else."

Not to be rude - but your explanation defies logic. 

Again - I am not asking about the flight plan or procedure (arrival or approach).  I am asking about one particular leg in which the MFD shows the correct waypoint, bearing, distance but the PFD shows an incorrect and never changing bearing and distance.  It has nothing to do with the flight plan.  

It seems to me you misunderstand what was meant above by "the flight plan system is screwed up".  What this means to me is the sim's ability to correctly follow a depicted flight plan is unreliable, i.e., 'screwed up'.  Your own statement that the MFD indications are correct, but the PFD indications are not, confirms for me the point that was being made above wrt to a "screwed up system".

I've been working with fairly sophisticated GPS/Autopilot/Navigation equipment for at least 20-years. I've spent many days operating many different GPS (and LORAN before that) systems in all kinds of weird situations.

MSFS defies logic sometime.  That's the point haha!

......and fly previous platforms that with the available enhancements are not so lacking.

Sure.. that is an option... while we wait for MSFS to be fixed.. 😉

But if you did see it do that, you would put an INOP sticker on the unit and send the airplane in for service.. which is kind of what we are suggesting here, or you can continue flying it and watch it at every step, so it does not kill you.. 😉

Brings to mind Rumpelstiltskin...
Or perhaps Sleeping Beauty is more appropriate....
