It could be that whatever you're using to view the .loc file is set to a different format for the co-ordinates.
Geocaching uses the format DD MM.mmm, which is degrees and decimal minutes, e.g. N 50 45.250 W 001 48.500
Another common format is DD MM SS, which is degrees minutes and seconds. In this format the above co-ords would show as N 50 45 15 W 001 48 30.
If that's the problem, you need to change to DD MM.mmm to see the co-ords the way cache pages display them.
