please take a look in my campaign reporting, here for one campaign.
I have about 4622 Visits in this campaign. By unfolding the campaign I see more data. But the visits in the broken down data ist much less than the 4622. As you can see on my screenshot I have 50 datapoints (10 on this page) - the other 40 on the other pages are only about 100 visits in sum… So - where is the other data? To get to the 4622?
