Wrong swim distance during exercise

Hi

During my swim since updating to 10.0 the distance seems almost double as if pool distance was set to 50m not 25m. But when I stop the exercise it shows the correct distance.

How can I solve the problem?
I want to use the distance during exercise without counting the lap.

So is this happening when you do a Lap Swim on the watch? I had a training plan on my watch yesterday 2x400yard and both seemd correct to me. Trying to figure our where you are seeing this incorrcetly reading, which i'm sure is happening with firmware 10. Also i've never figured out a way to just swim and have the watch add up the distance, without having to use a training plan or do the lap swim function.

Additionally to the inaccurate swimming distance recording, no intensity minutes are credited for swimming where previously there were.

Swimming distance now records accurately with firmware 11
