I don't use 1/2 mill charts anymore; the latest I have is Ed. 29
That may explain it. Ed 29 must be quite some years old; I would guess 10 years. Current is Ed 38.
The intersection names change from time to time. I got my PPL 11 years ago and have always been using those points on flight plans.
I got those names straight off the chart hanging on the wall above my desk, so they exist for sure.
What Skydemon shows or not is up to them, but showing intersections, particularly on FIR boundaries, is pretty useful.
