Fenix 5x plus - missing 100m lap times in the Pool Swim function

Dear Garmin,

When using the Pool Swim function I do not see the 100m times/statistics.

When running the wacht can autolap at 1km and while on the roadbike this is every 5km. 

I have tried to use the Lap button, but then the watch registers half my swimming as "rest" time.

The only way I have found to get these lap times is to press the Lap button twice every 100m. This I not handy. 

Is there any other way to do this ? 

In advance many thanks.
