Dropdown menu shows up on Home page but not other pages

@Teifi Looking at Chrome's dev tools, it looks like you have CSS on that page that is hiding the dropdown menu. I would update at CSS to the following:

NEW CSS

/* Change HEADER nav links on DESKTOP so it goes to home page instead of being anchor links on same page */
.header-nav-list > div:nth-of-type(1),
.header-nav-list > div:nth-of-type(2),
.header-nav-list > div:nth-of-type(3),
.header-nav-list > div:nth-of-type(4) {
	display: none;
  	margin-right: 0;
}

This will target the <div> tags that are direct children of the .header-nav-list element rather than ALL <div> tags.
