Gallery Not Working

I am using the Divi theme. I created a gallery of 15 images. I chose responsive gallery. I entered the shortcode in a code module. It only shows the first row of thumbnails and it doesn’t show the icon when you mouse over it. I tried to use a text module and clicked on the add foogallery button but the button turns almost solid white and nothing happens.
