Table Column Headers Not Appearing

I’m using the following shortcode to display downloads from a particular category

[wpdm-all-packages categories="scoreresults" order_by="title" order="ASC" cols="title|package_size|download_link" colheads="File Name|File Size|Download"]

But for some reason the headers are not appearing. This was working before, but after updating to 3.2.92 this appears to have stopped working.

I have since updated to 3.2.94 – and i’m still getting the same issue.

The following is the html source for when the headers are displayed

   <thead>
      <tr>
         <th style="" id="title" class=""></th>
         <th style="" id="package_size" class="hidden-sm hidden-xs"></th>
         <th style="" id="download_link" class="hidden-sm hidden-xs"></th>
      </tr>
   </thead>

Can you assist?

Thank you

Thank you very much
