Apple Watch ultra and Health app

I just got an Ultra and I’m interested in the calories information.

On the apple health app I see a number for active energy and resting energy.

I also see on the apple fitness app there’s a number for active calories which fills the ring that is the same number for active calories on the apple health app. But on the apple fitness app there is also a number for total calories on the day right under the active calories. Is there a reason why these are different.

example:

Apple Health App

Active calories = 500

Resting Calories = 1000

Total = 1500

Apple Fitness App

Active Calories = 500

Total Calories = 11000

the total calories for the day is coming up different in the health app and the fitness app.
