Apple Watch isn't tracking calories correctly

My Apple Watch doesn't seem to be logging my active calories correctly. When I do a workout, it shows up as a "workout" in the Watch app and tells me that I burned enough active calories to close my rings, but then when I check the Activity page, it says I've burned less calories in the whole day than I did in that one workout.

For example, today I burned about 100 calories at the start of the day, then went for a 7km run, and my run summary shows I burned 536 active cals and 579 total cals. But when I go to my activity summary, the watch app still says I only burned 442 cals in the whole day. I can see the run synced as a workout, but for some reason it is not tracking all my calories correctly.

I don't think it's because I'm using an external app to log my workouts, because I've been using this same app for years and have never had a problem until recently. Someone please help! It's frustrating that I'm working out enough but still not closing my rings.
