Trackpoints not shown

[grepnok]

I've just downloaded and tried RouteConverter.  I like it that it's a single jar file with no external dependencies.  I created a test gpx file using GPS Logger on Android.  Opening this in RouteConverter, I get the four waypoints I created, but no trackpoints.  I don't necessarily need a list of every trackpoint, but I do want the route plotted on the map to show where I went.  It's just showing straight lines between each waypoint, and I can't find a setting that takes the actual route travelled into account.
