Here the page-views shown are for the end of the 7-days period. I.e. 5.8k page views are for last 7 days (7-days period which ended today). And the 4.1k pop-up is the data is of 7 days, which ended 7 days ago, i.e.,
4.1k : Week that went week ago. [not 2 weeks ago].
Just an opinion, which might not be good enough to make the change.
