After manually editing an activity due to inaccuracy of recording on a treadmill, it isn't being reflected in my daily trackers (step count, floors climbed, heart rate, etc.). Why?

There have been a few times when I've had to manually edit an activity due to the Garmin device not accurately recording. For example, today at the gym, I was doing incline work on the treadmill and it consistently logged my heart rate as 94 despite me pouring sweat. I edited the activity on Garmin Connect to reflect what I actually did in terms of distance, incline, and heart rate (based on the treadmill's read). It will not log on the daily counters for floors climbed, step count, heart rate, etc. Why? Is there a way to fix this? 

Thank you in advance!
