Can you post the FIT activity? Is the FTP setting correct on the Edge? Is there a large power spike. Trainingpeaks will filter out large power spikes, where as the Edge as a recording device does not.
The problem is with the NP calculation.
Could you post the settings.fit file and activity profile that you used for that ride?
Sorry, I actually need the activity profile file.
I mean the sports activity profile, which is a FIT file contained in the Garmin\Sports folder.
