Since a few days I have a problem with the import of activities, originating from Garmin Edge 1030.
It shows such a power history:
The raw power plot shows two lines, one seems to be the accumulated power, the other could be the correct power.
In Garmin connect and in strava the power curve is correct.
On the top part of the activity page there is a link to Garmin connect. For those activities, where the problem occurs, this link is inactive, for the others not.
If I import a fit file without accumualted_power, everything is okay.
