List from point gets direction wrong

[+rogbarn]

I created a list of benchmarks for a distance of 20 miles using this url. In this list of 200+ benchmarks, I found two that are listed as North of my selected point but are actually South. The PIDs are HB0156 (18.6mi N) and HB0157 (19.65mi N). I checked the coordinates, state/county, description and they all point to a place south of my point, it's just the listing that says "N". The distance seems right although I have not checked it. What's going on? Is this some bug in Jeremy's software (certainly not!). Has anyone else noticed the same thing?

 

p.s. I just tried it using a zip code (62919, had to increase the distance to 24 mi) instead of lat/long and it came out OK, i.e. the distance is "South".
