[Plugin: Super RSS Reader] Multiple RSS feeds

I am trying to use multiple RSS feeds in the plugin, and I have been separating them by a comma, but it will only show the first RSS feed I put on the list.

Is there a certain way to separate the RSS feed URLs? I am not sure if I am doing it wrong because only the first feed I list shows up.
