Today, I noticed that my report of Total Distance has been adjusted and now displays the right total per activity! Hopefully it's here to stay.
Thanks Garmin
Based on your comment, I changed my activity type from running to walking in order to see if the activity time report changed. After waiting a few minutes, I refreshed my Connect page and the activity on the activity time report changed to walking. This is the first time it has done that properly since November 15th last year.
