[Plugin: NextGEN Gallery] Slideshow navigation not showing

Hi there,
Love this gallery plugin but having trouble getting the navigation bar to show on my slideshow. I’ve selected “Show navigation bar” in the Gallery>Options>Slideshow page. Am I missing something else?
The slideshow is at: http://www.localfilmcultures.ca/?page_id=434

Thanks!
