My wife just finished a 4.97km run with her Forerunner 45S. Apart from her data showing on the watch in miles rather than km in line with the watch's latest buggy update, her laps data doesn't make any sense.
Basically, even though it shows the distance correct at 4.97km, it shows 5 x 1km laps and a 0.97km lap, i.e. a total of 5.97km - so it's got an extra 1km lap from somewhere! You can even see in the picture below that the distances and times don't add up to the total, but there's no obvious duplicated lap.
The watch itself also shows the same - 4.97km total but 5.97km worth of 6 laps.
Anyone else seeing this?
