It's a Groundspeak issue, the problem is that when importing the geocaches on your device with the live functionality, Groundspeak does not send the corrected coords. Simple as that. Probably will take a few years to fix concidering the time it took to get this into their own official app..
To be honest I expected more because of the 'send to garmin' function. But as it stands the live option on the garmin is only usable for traditionals.
