Setting Global Menu bar and Header Image Not Working

I could very well be missing something but I have done my research and I just can't seem to make it work. So I went to my /blog page and I modified the Menu bar to add my site name and remove the word Spirit. I also added a new header image. Now I would like to see those changes go global across all of my interior pages except my homepage.

At this point when I look at the About page I don't see that my changes are showing up. I know that I am probably missing something here. Can you guys help me with how to make this work.
