Only the subtitle is displayed - Feeds not showing up on landing page

Hi,

Everything works fine when I create the feed, but once it is created and refreshed, I just have the subtitle of the feedpage which appears !
BUT, I do have the link "List items" below, and when I click on it, I go to a nice page with all my feeds, each with about 5 lines of description, and each linking to their own node.

So I don't understand why I have to click on this little link below to have the expected result (and actually I don't really know what should be displayed instead (Just the titles ?))

I am using the most simple installation:

Parser Common Syndication
FeedAPI Node

Do you have any idea what can go wrong ? Here is the feed I use for the test : http://feeds.feedburner.com/shaiya-online

Thank you very much if you have some ideas to help me,
Regards,
Xavier
