Why is my 'Players' and 'Locations' chart data not adding up in my Reporting Campaign?

In a reporting campaign, it is not unusual to see your chart data look a bit off under the 'Player' and 'Location' tab.

This is due to the data we're being sent from the publishers' tracking URLs. Depending on the ad server, we can receive duplicated data (duplicated IPs with the same timestamp) from the tracking URLs. The attribution job de-dupes the duplicates -- because, this is a reporting campaign, no attribution takes place to dedupe those duplicates.
