For what its worth as well, it could be the display resolution you have on the Oregon. If you go into the map setup, then advanced, then zoom levels, you can change at what level of zoom the waypoints display. This stops your screen being cluttered with waypoints at a "high" level.
I just went in and changed mine to 500mtr and the waypoints show as the type of waypoint you set (eg trailhead).
Much easier.
