Garmin swim 2 -heart rate zone chart blank

Hello

My Garmin Swim 2 heart rate zone chart is empty, even though it is clearly measuring my heart rate and has the zone data displayed in other forms.  Any clues??


First image is from Garmin Connect in my browser. Second image is screenshot from my phone.

  • Seems like a bug. Has this happened for other activities?

    You could try to make a small change to your HR zones, change them back, and see if that fixes the problem.

  • ... and if it happened just at this single activity, then the FIT file of the activity may be broken. The time in Zones is normally included in it. If you export it, and post here, we may be able to see it. If you have a similar activity which has the zones included all right, please zip the two files together, and insert the zip file here with the help of the function Insert » Video/Image/File » Upload
