I'm trying to set up my heart rate zones basing on %LTHR. Firstly, I switched from %MHR to %LTHR measuring method in Garmin Connect Web, filled the percentage of my zones and synced my device with Garmin Express. But the changes weren't applied on the device - I saw just out-of-the-box settings and values in the device "My Stats" menu, there were no changes which I made in GC. "No problem" - I thought, and tried to configure heart rate zones directly on the device. I wanted to set Zone 5 as 105% - 107%, but Garmin refused to accept values bigger than 100% and autocorrected 105% to 100% (see the picture).
Please, fix this incorrect behavior. Thank you.
