I just bought a new Garmin 235 and have done 2 runs in the last week, both of which have resulted in my training durations, calories etc, being doubled up when Garmin Connect sends my stats up to MyFitnessPal - it's exactly double each time, this morning showing in MFP that I have done '51 minutes of cardio' but it was actually 25mins 8 secs.
Is there a known glitch or could there be another reason why this is happening?
Thanks
