title: Data Filter Shows Nothing To Filter On
body: <p>I have imported a query into Excel, very straight-forward process.  The issue I am having is if I click the header row and say filter, if I select any of the filter arrows, their are no values to filter on?  What should I change so that I am able to filter on values in the columns?</p>
  
  <p>Row 1 contains header, row 2 contains data --- however their are a few blank values returned in the data row(s) (I.E. row 2 and beyond)</p>
  
  <p>Here is a link to a garbage data workbook showing the issue.
