Hi there Harlan,
Thanks for posting about your Apple Watch not tracking workouts exactly how you want. I'd be glad to see how I can assist.
A great place to start would be to restart your Apple Watch and your companion iPhone if you haven't done that yet. Check the links below for info on completing both of those.
How to restart your Apple Watch
Restart your iPhone
If the issue persists after that, you might want to unpair and then re-pair your iPhone and Apple Watch. Unpairing your Apple Watch will create a backup of the device on your connected iPhone.
Unpair and erase your Apple Watch
Set up and pair Apple Watch with iPhone
Let me know how that works for you.
Have a great day.
