title: Qlikview chart sorting doesn't always work for users
body: <p>I have several Qlikview charts that have interactive sorting enabled but the odd part is some columns can be sorted ascending or descending and others can only be sorted one way.  Nothing happens if you click on the column again.  </p>
  
  <p>Each field has a proper sort defined, it looks like a bug - anyone else experience this?</p>
  
  <p>Thanks</p>
