Hi, I’m trying to set the fonts globally as well and it’s not working.
My WordPress and Newspaper theme installs are relatively new. I’ve created a menu from scratch and set it as “header main” and it is not a mega menu.

Inside TD Composer, also created the header menu from a blank template and added the ‘header main menu’ element. I did not set any styling.

Then, when I go to the Theme Panel > font settings > header: main menu (and also top menu, mega menu, etc. just in case), and pick a serif font, the style doesn’t work on any element. When I test on the ‘body – general font’ it works. There seems to be an issue with the menu font styles for the header.

Am I building the menu wrong?
