no update of training status when using stored hr-date from hrm-Tri

Hello,

I have a Fenix 6x. Running on the actual stable Software 4.1

I am experiencing problems with updating the training load when I make an acitivity with HRM-Tri and downloading the heart rate data after the activity. I give the watch and the hrm-tri up to 10 minutes in the resume/save screen, but that does not help.

training effect is calculated in the right way but the Training load (8) is completely wrong:

Here is the activity:

https://connect.garmin.com/modern/activity/4137632556


and here is a similar activity where i was wearing the watch all the time - Training load 149

Is somebody else experiencing this problem too - should be the same for all Swimming activities? what are your thoughts about it.

many thanks for your help.
