Description for Meta Description Not Showing In Google? Optimizing All in One SEO Pack Forum

The words that I have in my All in One SEO meta descriptions isn't what's displaying in the Google Snippet and I haven't been able to determine why. I've used one of those online meta tag analyzers and they return all of my meta information so I would think Google could see it. What are the reasons why this would take place and how can I fix it? Is it fixable? The only thing I can see is that the All in One SEO meta information is positioned with the other meta information at the top of the section when I view source. An example URL would be: http://blackartblog.blackartde…..-beal.html and a search for "fruitful lashun beal" ranks highly but the snippet that displays is from the limited text and not from the meta description. Any advice? Is this a configuration issue?
