Navbar buttons won't change color.

Site: https://atproducts.xyz/beta/beta
CSS for nav-bar: https://atproducts-beta.netlify.app/static/nav.css

Thanks for maintaining Darkmode.js.
Once dark mode has turned on, the 2 dropdown buttons "Products" and "Communities", refuse to change color.
I need help because I'm trying to make Dark Mode work on this site.
