How to Center Navigation Bar?

Hi guys,

I went to in Parabola Settings, Graphic Settings (6th row down) there is a box ‘Menu Alignment’ choose Left, Center, or Right… I chose “Center” but it didn’t just work : / …

How to center my Navigation menu? I have a lot of pages btw… 9 pages.

I have 5 pages on top,
and 4 bottom.

I want it to be something like that
