Stacking navigation menu

Hey,

I am making a new design for our website with a staging site (thus not reachable). I have a header in the FSE fotball theme, but it keeps stacking although I feel like there is plenty of space. I have tried to widen all possible columns or menus, change font, change distance between the topics, put of the wrap to multiple lines option but it will just change but still stacked.

Thanks!
