I have no idea whats wrong: during running my heart rate is always in the red area, but it shows no area, like my pulse would be to low (but it shows thst its in the red area although my pulse is normal). When I sync to garmin connect its shown there wrong. I have 100% of my running in the red area.

I have my pulse areas in the connect app and synced it to the Fenix 5s. Since it broke a few weeks ago I think its a software flaw.

Has anybody an idea whats wrong?
