[Plugin: Featured Posts Grid] Trouble with back arrow

First thing I want to say is I love the plugin. It looks really sharp. I am having one small problem though. When testing everything I noticed after I go to my second page of posts and click the back arrow that most of my posts from the first page disappear. I can still hover over where the posts would be and the links are still there. I should also say that this problem does not happen when clicking the pips. They work fine. I really don’t know where to begin to try and resolve this issue. I could really use some help. Here is a link to the page I have up for testing so you can see what I mean:

Again any help would be great. Thanks
