I will look for it, but there is a known bug in waypoints that have over 6 characters. I complained about the same thing about three weeks ago and someone told me about it being a known problem.
I guess long names use to work, but it broke a few updates ago.
You can go in with an editor and shorten those name for now until the problem is fixed. The flight plan is a plain text XML file.
But the AP will still follow the flight plan even when it doesn’t show on the map.
Here you go, this was the same problem I reported and there’s where i was told that it is a known problem.
