I've seen the GPX file and I realised that it is indeed very oddly written. Basically the file has 2 tracks.

The first track worked out as per normal, with (I think) 2 track segments each with a bunch of points. I believe that is the normal looking line that we see towards the southern part of the map in the screenshot.

Yet, in the second track, there are thousands of track segments, each segment containing only one track point. Each track segment alternates between a different day (e.g. trackseg 1 is day 1, trackseg 2 is day 2, trackseg 3 is day 1)

If you zoom in far enough, the opaque area isn't actually opaque, its tightly packed lines that goes back and forth.
