Strava sync HR issue

Hi

I just started using this site this month and am still learning how to use it. Now I have uploaded my data from strava with indoor cycling. For some reason strava does NOT get my HR data correct. It shows for example 1hour 15 min time recorded HR but the total time only gives 15 min.
How can I change the total time in the workout uploaded to the full 1 hour 15 min instead of only 15 min?

BTW I now know how this issue started as Garmin watches standard use “smart recording” of saving your data of any workout. As soon as I disable this the data shows the correct total time.

If it’s smart recording, there will be a warning above your activity charts.
