I have my 5 month old 255 watch set to Pool Swim. It just started to take each set and upload them as multisport. One swim session turns into 12-16 activities - super frustrating!!! It did something similar during a strength training session in the gym. I start the watch at the beginning of my workout and don't touch it again until I am finished. Auto Pause is set to ON. This only started happening after a recent update. How can I fix this?
