I just noticed for some reason the slider isn't showing the last post that it should be. For instance right now I have it set to show 4 posts, and it's only showing 1-3. If I set it to show 5 posts, it doesn't show the 5th. If I set it to show 4 posts with 2 slides (8 posts total) it doesn't show the 4th post, or the 8th post.
I probed a little deeper and it seems the last post wraps underneath to a new line and turns invisible (???)
Here's a picture to show you what I saw: http://i.imgur.com/hg1S5Az.png

It only started doing this after I added the floating social bar plugin, but it doesn't go away even when I turn it back off.
