HRM Pro heart rate from a timed activity - Open Water Swim - not registred in daily heart rate timeline on Garmin Connect

Hi everyone, 

I am wearing a HRM Pro and a 945LTE while doing Open Water Swims. The monitor works fine and transmits the data to the watch and consequently also to Garmin Connect. I can then evaluate the performance when accessing the timed activity. 

What baffles me, is that the data from the timed activity does not appear on the daily heart rate timeline on Garmin Connect. A gap is simply appearing from the time the timed activity was conducted. It also means that the daily "high" heart rate is wrong as it does not take the data from the swim into consideration. The data from the activity does not appear in "Intensity Minutes" either. 

Not the biggest problem, but I would appreciate any help to solve the issue.
