Pivot Table Slicer Not Showing Pivot Fields as Option to Filter

[LSlisher11]

Hello,

I have a report that has slicers that filter by the count of an identifier in a pivot table.
However, when choosing the options for the slicer, the values aren't filtered properly.

I tried to recreate the slicer and when I went to the ribbon -> PivotTable Analyze -> Insert Slicer, the raw data column headings for the pivot table are shown as options instead of the pivot table fields.

So the field of the pivot table that I want to filter does not populate in the slicer options window.

This slicer is macro generated along with other slicers that all seem to work correctly.
