It was working great, but suddenly on a run yesterday, instead of Distance / Timer / Pace, it showed two different data info I never saw before. Today I am trying to reset the data screens. Went to Start button (top right) > Menu > Activity Settings > Data Screens > Screen 1 > Distance/Timer/Pace. This is exactly what I want. I hit the back button until the "home" screen with the current time. Pressing the top right button it shows Run, but then NOT the screens or data I chose. Instead it shows Heart Rate and HR Zone. Not what I want. I have gone back through the process / steps mentioned above, time and again. But when I press the Start Button again, I do not get Distance/timer/Pace. I get HR Rate / HR Zone, no matter what I do. Can anyone tell me what I am doing wrong? Thank you.
