Workout calories not equal to move ring

Kinda hard to explain this issue but here I go. Since updating my phone and watch to the most up to date software (iOS 13 and WatchOS 6) I have noticed that if you total my calories up from each workout it is more than what my watch is showing for my total move calories. For example, last Saturday I burned 2,073 calories on a bike ride, 486 calories in a lifting session, and then 170 calories while on an outdoor walk. These on their own add up to 2,729 calories, however my move ring showed 2,651 calories. Usually I get another 300-400 a day from just general movement (i.e. walking at work, basic movements, etc).

Has anyone else seen the math not adding up since updating? I know this isn't a huge issue, just found it a bit off
