Problem with repetitions counting in Strength activity

Hello,

Software version: 14.40

I noticed this kind of problem lately (don't know if it existed in previous versions of software):

1. Doing Strength activity (lets say dumbbell lateral raise), 10 repetitions, watch is counting them about right. Saving activity.

2. Doing new Strength activity, the same movements, watch is not counting any repetitions. Discard activity.

3. Rebooting the watch.

4. New Strength activity, watch is counting repetitions  right again. Saving activity.

5. Another Strength activity, the same movements, watch is not counting any repetitions.

Anyone have similar observations or is it just my case?
