why polar h10 is not shown on the activity page

hi,

I have a forerunner 945 and I have 3 different HRM strips 2 garmin and 1 polar h10. When I do activities with my garmin strips they are shown automatically on the activity screen as additional accessories which was used at the given activity on the right side below my watch. However when I use the polar strip it is not shown on the activity page meanwhile I can see that the HR data was successfully measured, captured and transferred to garmin connect (the wrist heart rate is disabled on my watch which means the polar strip works very well). but I cannot see the polar strip or any other sign that the heart rate was measured by external HRM strip on the right side below the watch as usually for garmin strips.

Is it normal?

Thanks,

Imre
