v2.5.5 – Missing Options

I’m building an update to my current site and decided to use Hueman again as it was such a great theme. My site’s previous version uses Hueman 2.1.4 and I LOVE it. However, updating to 2.5.5 for the new site it seems heaps of options are missing.

I can’t find where to add a body background image or a header image and there there seems to be no option to enable custom CSS. Am I missing something here or have these options been taken away?
