Anchor links does not work from other pages?

I'm building a new website and are using upfront and Spirit and I have some trouble with my global header menu.
The structure of the site is the same as Sprit and I'm trying to make an anchor on the start page to testimonials down below. That does work on the start page and it does scroll down.
But on all other pages it will link like this to testimonials: if I'm on the blog page should it not be like this or?

Hope you understand it's a bit hard to explain.

Best regards
