Updated Post, But Old Info Displayed

Hi, great plugin, but having an issue. I’m displaying items on our News page, from the News category of our blog. I’ve updated (edited) a post, but the News page using the plugin still shows the old preview info. The post on the blog is fine and up to date. (I am not using Excerpt on the posts). The plugin appears to be caching outdated info. How to clear it and get it to show the latest updated text of a post?

The page I need help with: [log in to see the link]
