Those blue ones are the measurement, for example in this pivot there are two measurement: Total Sales and the Number of Sales and currently only Tota Sales is active, the Number of Sales is in the waiting list on top of pivot. If you drag the NUmber of Sales to the measurement area, the pivot will show result of Number of Sales as well. If you do not need to Number Of Sales you may remove it in the settings of Pivot.

Hi Gary,

If you only want to hide those blue fields, please add the following css rule to your page or to pivot/assets/PivotMatrix.css:

.krpmDataField {
  display: none;
}
