I managed to import my FitBit data to Garmin Connect. Everything went fine.
Then I saw, that the kilometers are not like 12,52 kilometers, but 1252,00 kilometers. So I went 300.000 kilometers in 9 months. This is a huge error in my statistic I want to get rid off.
Where can I delete these imported data?
The tooltip tells me, that a new Upload / Import overwrites the old data. But I tried to upload modified files, it works (Import successful), but it doesn't change when I refresh an imported day (still the first data visible)
