title: Clarity Datagrid custom filtering isn't working with more than one filter
body: <p>I created the non-working sample application here:
  <a href="https://stackblitz.com/edit/clarity-light-theme-v2-dwqmgr" rel="nofollow noreferrer">https://stackblitz.com/edit/clarity-light-theme-v2-dwqmgr</a></p>
  
  <p>The Role filtering is working, but the Group filtering is not.
  The weird part is the datagrid is showing as if it is filtered, however the event sent as part of the clrDgRefresh does not have the custom filter for the non-working filter.</p>
  
  <p>Does anyone have any ideas what I'm doing wrong?</p>
  
  <p>Thanks!</p>
