header menu not aligning

hello I need help with figuring out why my main header menu is not aligning the way it is set to. I cant figure it out.

It is supposed to be centered under the logo. That is how it is set up in the header builder.

I tried changing the css like this:

.nanospace-header-section .menu {
    

    align-items: center !important; 
}

that didnt work. i cant figure out where the menu is getting told to align left. would appreciate any tips.

thanks
nisa
