LOL... guys I KNOW how to use Icons. I've changed the icons everywhere else. The problem is with the Artificer theme overriding everything I do in the Site Sidebar.

Not to be rude, butlLike I said in my original post - "Because you overrode the standard navigation engine, it completely ignores standard system classes like col-red1 and blocks global style overrides. Why did you hardcode asset pathing and lock users out of basic menu customization?"
