in garmin connect;
- create a new strength workout in "connect"
- make sure there is 2 round "loop"
- set first entry to excercise
- set the excercise to "curl"
- target type "lap button press"
- weight to 10.5kg
- set second entry to rest
- name it "debug"
- send to device.
on the FR255:
- Start activity "Strength"
- select workout "debug"
- press start button -> do workout
- press start button again -> start workout
- press lab (back) button
- set any repetition count
- press start
- ->>> Weight 10kg is shown and only integer values are allowed to enter.
- if the weight is not changed, it will be stored as 10.5 kg even if displayed wrongly.
This bug exists since the 12.x firmware and it is super annoying.
