Vantage Slider

I’ve just installed the Vantage theme and am having some issues getting the slider to use anything other than the demo. I have installed and activated the Meta Slider plugin, and when I go to change the slider under Theme Settings -> Home, I see the option of using the slider I created through the plugin, but when I select it, it doesn’t change. I also get no change after I set the slider to ‘None’ (I get the default slider no matter what).

Can anyone suggest some things I could try?

Thanks
