waypoint unit incompatibility with Caltopo and Garmin etrex 30?

Wondering if you can shed some light on a situation that I have noticed with my Garmin that essentially interprets the waypoints that I have auto-populated along the route every 0.1 mile to read every 10 ft?

Let me give you an example. https://caltopo.com/m/24JT
This map has been auto-populated with points every 0.1 mile. After importing to my Garmin, and approaching the trail, the etrex unit will ping every 10 ft, telling me of the next waypoint, essentially misinterpreting the distance between waypoints established. This has happened the last 3 times I have used this unit since around September 2017 (prior to that, was working fine)

Might there be a quick fix to this? Garmin tells me that I need to use basecamp and then redraw the map, putting in waypoints as needed.

Thanks in advance for your insight.

    It looks like you're confusing routepoints and waypoints. You've set a waypoint ever 0.1 mile, but the actual line has far more points.

    Looks like you either need to edit the line on CalTopo and set the GPS type to "track", or resample the actual route so that it only has a vertex every 0.1 mile (right click -> modify -> resample).
