RSS Widget does not Display Author

I am using a Yahoo Pipes mashup as the Feed for the RSS Feed Widget for the sidebar. The problem is that the widget does not display the author’s name even though the author is present in the feed.

You can see it from the empty <cite> tags in the HTML: https://new.acperience.net/

The feed is at https://pipes.yahoo.com/pipes/pipe.run?_id=506a2ad0816daa257c1f4e76977e7a6a&_render=rss

Thanks.
