Apple Watch ultra active energy question

In the health app where it shows steps, active energy, etc. when I tap on active energy and scroll down to show all data I noticed today there were 6 different times where it totally skipped one hour of tracking time. In result it’s showing I’m 200 calories burned behind at this point in the day where I normally should be. I also notice on some other days it’s skipping an hour here and there. Why is it doing this? The watch is snug on my wrist and all my information is up to date. What can I do to fix this? Really starting to get aggravated with it.
