Guayadeque Does Not Show Contents of RSS Feed

I have set up two podasts in Guayadeque. Both are set to download all and allow delete of old items.

The first:
NPR's Morning Edition
RSS Feed:
http://www.npr.org/rss/rss.php?id=3

The second:
Science Friday
RSS Feed
http://www.sciencefriday.com/audio/scifriaudio.xml

Science Friday shows every podcast in the list as it should.

Yesterday, Morning Edition showed only the first item in the feed. Today it shows nothing at all.
