Ever since I have owned Garmin Edge products (500, 510, 530) I have had the practice of every few months hooking up to computer via USB and backing up all files in the "Activities" folder. Then I delete all the files in the Activities folder on the Edge unit. I did this today on my 530, but when I navigate to my history - All Activities it still shows about 30 activities. Some go all the way back to 2021 when I got the 530. The most recent is from April 2023. I confirmed after this that the Activities folder is empty when I hooked back up to computer. I told computer to show hidden files and still nothing in the Activities folder. Where are these activities living on my Edge 530 if they're not in the Activities folder? Should I keep them or delete them?
Additional detail: when I look at these activities, there are only Summary, laps, and upload options available for them. Summary appears to have all the info, but Source says "Garmin Edge 51".
