I guess this is more a Garmin Connect issue, than Swim 2.
Every so often, my Swim 2 mis-calculates the number of lengths. In Garmin Connect, I can edit the total distance swum in the session, but I can't edit the incorrect distance in the actual set, that remains incorrect. It messes with pace calculations and records etc and also uploads the incorrect distance to Strava. I don't understand why the total distance can be edited and not the set distance. it drives me insane. Please fix this. Thanks
