After you create an Excel 2010 pivot table, the source data may change. New items might be added, and old items are sometimes removed from the data.
In this example, the East and Central regions are merged, and the Central region name is replaced by “East” in all the source data records.
After changing the data, if you refresh the pivot table, the Central region data disappears, but its name is still in the Region drop down.
To fix the problem, you can change the Retain Items setting in the pivot table options, to clear old data from the pivot table drop downs.
