Problem when uploading fit file generated from Amflow bike via Strava

Hi, I recently bought an Amflow bike, which can sync the activity to Strava automatically (a shame it can't be done to Connect), If i download the the fit file from Strava and tried to upload to connect the maps shows an erratic drawing always in the same direction, the rest of the data seems correct but the track don't.

Has anyone face something like this before?

Thank you!
