Hello there!
First, great theme!
I have installed the theme on our existing WP site and I cannot edit any of the Sliders that are there. I even removed them all and tried making one from scratch and I cannot even save the General Settings. I could not find something specific on a forum search with “Layerslider not saving” so I posted :(
Hey!
You have LayerSlider as a standalone plugin, either disable it or disable the Enfold bundled one – http://kriesi.at/documentation/enfold/deactivate-the-layerslider-plugin/
