Hello Beary82,
Thank you for posting in the Apple Support Communities. I understand that your Activity Digital Apple Watch face shows an incorrect amount of Move ring calories, and I’d like to assist you.
First, try restarting your Apple Watch, changing it to a new Apple Watch face, then try changing it back to the Activity Digital face. The support articles below can help with these steps:
