Navigraph fllight plan being ignored after way-point not in original flight plan

I am having a beginner issue with Navigraph. I have paid up so using the official version. I have simlink running and charts loaded. Can create a flight plan and see it in my FBW A320 Fly-By-Wire on the in-game iPAD. Everything loads and works as expected. I then can use my A320 MCDU (PU Air Korea) and import and edit the flight. However the imported flight plan has way more way points than are shown in Navigraph. These additional way points look OK and seem to make sense. They mainly appear when I set the departure runway ILS plus SID and arrival runway ILS plus SID.

Then when flying I turn on AP1 and everything works well until I get to the first of these waypoints. The Flight PLan on the MCDU shows N ¤ N where I would expect to see speed and flight level. (as a software engineer I read this as NaN or Not a Number). The aircraft makes no course change and flies straight thru the way point. It continues to ignore the flight plan from then on.


You can see my plane leaving the set route in the images above. What am I doing wrong?

Here is my simbrief screen for the flight:

EGKK/26L BOGN1X BOGNA L612 BENBO UY47 DRAKE L151 SITET UN859 SOPIL DCT BALAN DCT EVPOK DCT NARAK NARA8N LFBO/32L

I think I might have figured it out. I plan using current time (New Zealand so 12 hours ahead of UTC). I go to fly and of course the UK is in the middle of the night. I use the slider to go back to about 1:30 pm , so about 11 hours earlier. This gives me daylight, but is this what is causing the flight plan to screw up?
