Please see How Are Heart Rate Zones Used With My Garmin Device? for the best explanation
I think it means that your current pulse is lower than even the first zone.
Can you confirm that HR zone 1 was set higher than 126 at the time? Is this still happening?
If so, may I have permission to view your Connect account and reach you via email?
I resolve that. Watch messed up my zones. Everything was bellow zone 1. What is the difference between running zones and resting zones
