Changing metrics/results on tailor made workouts

I have set up my own workouts on my 935. It was for a circuit type workout which Involved lots of running, press-ups, up and down stairs and various other things. I set up a tailored workout in ‘Cardio’ and as I was going through the workouts hitting the lap button to register going on to a different movement. The metrics/results I got we just inaccurate reps for each exercise, when I want especially times and whatever else I can get... Any ideas?
