New update - lost ability to set swim lap length

[TriniteUK]

Hi, 

Since updating my galaxy watch software, I cannot change the lap length or any settings in my Samsung Health exercise widget. You click on an exercise and it immediately counts down and starts. No ability to modify screens, or change lap length. 

Any suggestions or help available? 

Thanks

It doesn't work for the galaxy fit3  at all. 

I need to change the pool length to 18m.
