Why there is a huge page views discrepancy on Summary Revenue reports

We noticed a huge page views discrepancy on Summary Revenue reports. Total page views on by day breakdown is very different from by placement breakdown (almost twice). Account: Spine Media - Network 1) Go to the report Revenue Summary 2) Select yesterday in datepicker 3) Select By Day breakdown 4) Select By Placement breakdown 5) Compare total pageviews on by placement breakdown with pageviews on by day. They have a major difference (almost twice). We'd like to understand what causes this discrepancy, which are the correct ones and what should be done to fix this?
