multiple categories, only displaying first one

I’m trying to parse a delicious feed. When I use hungryfeed it only shows the first CATEGORY and I want it to show all of them separated by either a space or a comma and space.

This is the shortcode I am using.
<table> [hungryfeed url="https://feeds.delicious.com/v2/rss/jharnwell/bundle:Stage%205%20%3E%20Number%20and%20Algebra%20%3E%20Linear%20Relationships" template="1" feed_fields=""] </table>

This is the template:

<tr><td width="100">
<a href="{{permalink}}"><img src="https://www.bitpixels.com/getthumbnail?code=15096&url={{permalink}}" /></a></td>
<td><a href="{{permalink}}">{{title}}</a> - {{description}}
<br /><font color="#999999" size="-2">Tags: {{category}}</font></td></tr>

This is the output from the delicious RSS feed for one item.

      <description>Drag a point to change the gradient of the line. To move one unit to the right, how much do you go up or down?</description>
