I’m new to using this watch but not the chest strap
I have done two self-made workouts using HRM Pro and FR265. After the workouts when viewing the HR chart, it shows a white line which I think is supposed to be the target HR along with the actual HR data. (Only included picture of one workout)
The issue is the white line goes straight across the chart and suddenly makes a right angle to the bottom of page about mid-workout. It’s an interval workout and target HR is zone 5 and no target for the recovery periods.
Is the problem because I didn’t program a target HR for the recovery periods? I didn’t want a target in case I wanted to use zone 2 & 3. Is it a bug in the system? How do I fix it?
