Different Menus (Dekstop) on Front page vs other pages

Hi Generatepress,

I am trying to edit my header. I do so by going to
"Customize" - "Colors" and then "Primary navigation" but the effects only affects the pages I go to from the homepage. The header on the first page is not changing at all.

Why is this and how do I fix this? :)

So for example going to:
/about/
you see a total different background color then on the homepage

Thanks in advance!
