My Venu S2 is no longer tracking my workout sets, when I hit the bottom button it just says "lap" as if I am running but am in the strength activity. Up until today when I would hit the bottom button it would track a new "set" but is no longer doing that. I turned my Garmin off and on, and double checked the activity and the data screens everything seems to be the same. Really want to be able to track my sets again! :(
