Workouts recorded on the iPad are not displayed in the "Exercise Ring" in the Health app.

When I record a workout with iPhone, the workout is displayed in the exercise ring. But not with iPad. A workout from iPad is recorded, it is in "Health" app history, but the exercise ring does not display it. Why is the workout not displayed on the exercise ring on iPad?
