Potential Refresh Issue

Hi there. I'm using bp activity + and I love the idea of the plugin. However, in my current implementation, (http://startupteamup.hotdinosaur.com) the activity + posts require a refresh before they show up in the timeline. I'm not sure if this is a plugin or javascript conflict with another plugin or if it's simply not a feature yet, but I'd love to get it working like the regular activity stream posts do. Thanks.
