Duplicates from Strava & Garmin

What is the easiest way to remove the duplicates? I already disconnected Garmin again but the old entries are still in there.
Thank you

You can use the Activities Table to check and delete them. Alternatively, if you only have a few activities on the system, you can reset your account and resync your Strava activities, then leave Garmin Connect configured to pick up your latest. The system normally will detect duplicates and properly manage this for you.
