!deathreset edits !deathadd, not !deaths, only !deathadd edits !deaths, so to see the !deathreset change reflect on !deaths, you need to call !deathadd at least once, which will add one death to the counter.
!deaths gives you the total counter, it’s just text !deathadd adds a death to it’s internal counter and edits !deaths !deathreset resets the !deathadd internal counter to 0
