How to delete specific rewards in Samsung S Health?

[anon(10000400)]

A few days ago I accidentally recorded a yoga activity during the night, and it lasted from the moment when I went to sleep to the moment when I woke up, resulting in my most active day (329 min).
I deleted the recorded activity, so there is no log in Yoga's specific trends or rewards, but at "be more active" (basically the general page) this day is related to my "most active day", with 329 minutes of activity.
There is any way that I can delete this specific reward (maintaining the others)?

Thanks

Hey - were you able to fix this?

Not yet.
To be honest, I did everything I could imagine to do (basically what I said in the first post) and now I'm kind of resigned, not trying anything else.
