When from the dashboard I look at Entry pages and Exit pages using the "simple table" (default) view, it shows me the number of entrances and exits. But if then I click on the bottom-left treemap icon, the visualization is wrong compared to the previous numbers. The visualization draws areas depending on the unique page views for each page, not its entrances or exits.
