Sorry no. One interpretation, especially on this site, is that the problem was some kind of database bug, maybe where the same location was entered twice and a tiny location error ended up creating two locations.

I expect that out of any random sample 500 million literate and mentally healthy English speakers, more than 450 million of them are totally unaccustomed to thinking about nautical miles ever. Even people in science, or even who might have dealt with nanometers in school do not typically think about nautical miles unless they are sailors or airplane pilots.
