Not all sites loading in Feed List

I have been secretly suspicious about this for a while, but finally got confirmation today. It seems that not all of the sites are loading in the Feed List window. For example, when I click on in the site panel, it shows 2 unread stories, one which was posted today at 12:12 am. When I go to the Feed List and scroll down to 12:12 am…nothing.

some proof I am not crazy:
