@Con-Hennekens Lat and Lon aren't actually flipped, just the order in which they happen to be present in the file differs from the routepoint to the trackpoint. For both, lat is still 51.x, while lon is 5.x, so no we're not in Somalia.

And like I said, I don't think there's a black dot at all, just the overlap of two semi-transparent lines. There's no "black dot" at the start of the line.
