I am attempting to implement the theme I purchased,

I am attempting to implement the theme I purchased, however, the options under the "Branding" tab in the theme do not appear to work.

Specifically, the below items do not seem to function:

"Insert your logo full url here"
"Sign up feature text"
"Sign up button text"

The URL to the site is: aspireservice.org

Might it be a permissions issue?
