Which HR monitor? The HRM-Pro/Tri/Swim have a history of being problematic. If you attach your fit files here, we can take a look and try repair them for you.
HRM-Pro/, Tri, and Swim will sometimes corrupt activity fit files
Update the HRM firmware How Do I Update the HRM-Pro Software Using the Garmin Connect App?
Note that HR data download after the activity is usually for swimming or when for some reason you could not wear your watch during an activity.
During the HRM-Pro download process keep the strap and watch in close proximity
If issues persist even after the firmware update, contact Garmin Support

Ok then...
we can take a look and try repair them for you.
I had exactly the same problem yesterday after the training , could you get your file repaired?
thank you, i guess that when i uploaded the heart rate from the hrm-pro it corrupted the fit without adding the heart rate data: i noticed it when I used the fit file repair tool, the heart rate data were not correct.
I used the HRM-pro because, when doing inline skating, the watch reception is missing heart rate data because our arms lean on our back. So after the training, i download the heart rate from the hrm-pro using the recommended Garmin procedure. That makes me 2 activities duplicated on garmin connect (because the watch already synchronized the initial one) but i suppress the one with missing heart rate data.
It usually works like charm except yesterday .
thank you for these advices, concerning the FFRT actions, i cannot state much since the training file was "missing" heart rate because of loss of HRM sensor reception (it actually switched to the watch sensor):
When i exported the file, the corrupted header was fixed. I tried again the upload, from the "activity" menu of my watch, the HR but it does not upload anything (i guess because there not longer data for this period of time stored on the HRM-pro).
Hey sorry for the late response..
Thanks
