First exercise reps change is not persisted

[autonome]

Steps to reproduce:

1. Start workout
2. On first exercise, increase the reps
3. Finish workout, close app
4. Next workout, reps are back to 5

For other exercises after the first one, the reps modification is persisted.

Seems like everyone affected by it, it's kind of annoying.

I've checked, problem still present in latest ios app update.
