In each column there is a number that shows the amount of content in that column. But it's wrong. It only tallies what is visible. If you click MORE then you can count all of the content in the column.

We use this column to quickly scan how much content we've delivered to the client that month and how much more we have left under our monthly scope. It's given us a panic multiple times to think we have under delivered, when really the tally on that column is just wrong.
