@FitOrlaWelcome.. Your Blaze activity has most likely got the calories correct.. When you added the Exercise manual activity it has overwritten your effort and lowered the calories. I would delete the Exercise Activity.
I would then create an Activity Record for the treadmill duration and that will show the calories expended then check your Active Minutes.
Then recreate your exercise activity with the calories shown from the Activity Record. You can leave the Activity Record there.
