Can't Get the Parallax Slider to display

I am brand new to WordPress and am not code familiar. I am using Evolve Theme after giving up on another one and am having a horrible time trying to customize the Parallax Slider. Everytime I change it on the dashboard (even turn it off) it still shows the original stock photos and explanation. The same is true for the Front Page Content Boxes, everytime I change them they just say array.

Again I’m brand new to this so apologize for the probably very simple question.
