Can Find the Background Options?

Hi, I just downloaded GP Premium, installed the plugin, activated the plugin, and then poked around for a bit.

It seems that I'm missing a bunch of the sidebar options that are displayed in the Video. I've got Generate Press set as the theme, hit customize, and the only options that I see on the left sidebar menu are Set Front Page, Header Content, Layout, Colors, Typography, Blog, and Widgets. It seems like I'm missing some stuff.

I'm sure I'm doing something wrong, but not quite sure what it could be?
