Apple Watch Tracker Confusion

I've read some posts that are 5 years old, but I'm still not seeing what I need.

I have the app synced with my Apple Watch. My watch is also connected to my stationary bike. I started my Apple Watch to track my workout (indoor cycling), but now I feel like I double-logged and shouldn't do this.

I have three entries:
1. Cycling (Apple Health) - which is correct and the one I want to keep
2. Cycling (Apple Health) - which is incorrect (different kcal) and I want to delete
3. Active Energy Balance (Apple Health) - which I don't even understand.

The only way to delete the last two is to disconnect my Apple Watch, which I don't want to do since I want it to count my steps and other activity.

Two questions:
1. How do I delete these two items? If I can't, then my kcal burned today is 3x what I actually did. If I disconnect my Apple Watch, it will delete them, but then I lose the benefits of connecting my device.
2. Should I not engage my Apple Watch in exercise and only let it count my steps? In other words, when I go for a 4-mile walk, should I not start the "outdoor walk" feature on my Apple Watch?

Please advise. I am enjoying the app, but this is not helping me track my daily exercise and accurate kcal count properly.
