PH100: Direct-To not finding my route waypoints

[elcapitan]

Direct-To waypoints are not recognized in FMC.  The route is loaded correctly and I can see it when pressing the flight plan button (FP) and the plane flies the route fine. However, I am unable to Direct-To any of the waypoints in the plan.  I made sure the nav database is up-to-date with the latest AIRAC 1804 (Navigraph) and I double checked the cycle_info.txt and it is showing the right cycle and date.

When trying to Direct-To a waypoint within 23nm, I enter the waypoint in the Direct-To screen, but when I press enter so I can activate the waypoint, the waypoint disappears as if I didn't enter it; thus I can't activate it.  The waypoints are not new, so I doubt the issue is related  to the FAQ question "Q. I can't enter a new waypoint into the flightplan using the FMC's keypad."?
 

Thanks,

The plane uses the default FS autopilot for VNAV.  Check to confirm that there isn't a problem with the Garmin autopilot on a default aircraft.

Thanks scoobflight, 

You are right, I am having this problem on default aircrafts as well.   I tried updating FSX waypoints through World Navids (http://www.aero.sors.fr/navaids3.html) but still the default aircraft flies the route and I'm able to see it in garmin but direct-to doesn't recognize any of the waypoints as valid!  

Direct-to works fine with some old waypoints I guess but not the newer ones.  Any ideas what I should try next or where to look?

Thanks,
