Activity display

If I go to my profile and set a target of 200kcal for my activity level besides the BMR then it will show up in the Diary under Energy Summary as 164 kcal burned through activity.

Why is that? It is not intuitive at all. I want it to be the same number everywhere. How do I do that?

If I select Moderate Activity instead of Custom activity level then it is displayed under my Profile as 894 kcal used as activity. If I go to the Diary it is displayed as 733 kcal burned through activities.
It doesn't make any sense. I am not using any Imported Activity.
