Problem with special text plugin

Please have a look at my site http://www.satvoices.com, scroll down to the “KITTY” and the “president bush” voices and notice the nice little blue and white text box panel is missing for them which leaves the html for the text box showing thus looking real ugly like.Any ideas why this is happening to just these also on the Garmin voices page it’s even worse many are missing, how can i fix this, thanks people!
