How to remove meta descriptions from K2 theme?

Hey. I have installed the All-in-one SEO pack plugin, but realize with K2 it leaves an extra meta name “description” tag. I’m trying to figure out how to remove the original description tag so that only my custom tag created with the plugin is shown. Where do I start with this?

automorrowmusic.com is the blog address. On any of my pages you can see the two descriptions when you view source.

Thanks in advance!
