How do I edit/delete a manual entry from Sleep Analysis on the Health app?

So I noticed that the Health app wasn’t tracking all of my sleep and decided to enter the correct information manually. However, when you enter the “start time” for a given day’s sleep, you also have to manually change the date for the “end time”. I didn’t notice that, and started modifying the start time for my sleep from 3 days ago, while Apple set the end time’s date to be today, by default. The result was that the app now shows that I’ve been asleep for the past 3 days 🤦🏻‍♀️ This isn’t showing up in the Show Data section, maybe because I entered it manually. How can I edit this?!?
