explorer and navigation page views do not add up
I have set up reports for specific page urls on a website that constantly has new datasets uploaded. Some of the datasets are receiving no traffic. So I have some reports that show a flat line in "explorer" view with no traffic at all, but if I click the "navigation" tab it shows entrances and exits. How can this be? If there were no page views, how could there be entrances and exits? (or previous pages/next pages)?
I also notice that when a page shows no traffic, the report does not show the page uri at all, but when I expand the dates to show some traffic, then the uri shows up. Very confusing!
