On my data tab I've got a column for "review date." Some of those cells are blank. When you go to the pivot table, the respective cell for that blank.review date cell displays the date 1/29/14. There is no data in the cell on the data tab, so why would it be displaying 1/29/14? I want it to either say "blank" or just be blank. It does this for every review date cell that is blank.
