Power and calorie issue

Since January 28th, I have burned more than 12,000 calories, which seems abnormal.

Similarly, in the morning when I wake up, my watch shows that I have burned more than 4,000 calories.

As a consequence, the power recorded during my runs is also unusual (average power 2,960W and maximm power 4,000W).

Has anyone else experienced a bug with the watch regarding power and calories burned ?

Thank you in advance for your answers.

Sincerely,
