Apple Watch resting calories incorrect during workout but correct at end workout

My Apple Watch Series 4 has always worked great, especially tracking my workouts. Since the last update I’ve noticed that during the workout the resting calories being burned are recorded as incredibly high and blatantly incorrect, but when I end the workout the resting calories display as what I would expect the accurate count to be. For example, during the workout my active calories will be at 50 but the resting calories will be at 450, but if I end the workout the display will show active calories 50 and resting calories 80.

I’ve already repeatedly checked health/workout settings (none of which have been changed), restarted my phone and watch (together and separately), and neither require software updates. Help!
