Why are my active classes not working when i use the media screen?

Question

I'm using React on this application and I don't know why I'm having this problem. I created a navbar with some active classname in the links so when the link is active they turn to bold. It's working perfectly when I have the normal screen, but when I try to use a media screen it only works for my first link (home) and I don't know why this isn't working for the rest of the links. So here is my code:

• HTML:

  import { Link } from "gatsby"
  import Logo from "../assets/Logo.svg"
  import "../styles/navbar.css"
  
  const Navbar = () => {
    const [show, setShow] = useState(false)
  
    return (
      <nav className="navbar">
        <Link to="/" className="nav-brandLogo">
          <Logo />
        </Link>
        <Link to="#" className="nav-btn" onClick={() => setShow(!show)}>
          <span className="bar"></span>
          <span className="bar"></span>
          <span className="bar"></span>
        </Link>
        <div className={show ? "nav-links show-links" : "nav-links"}>
          <Link
            to="/"
            className="nav-link"
            activeClassName="active-link"
            onClick={() => setShow(false)}
          >
            Home
          </Link>
          <Link
            to="/projects"
            className="nav-link"
            activeClassName="active-link"
            onClick={() => setShow(false)}
          >
            Projetos
          </Link>
          <Link
            to="/team"
            className="nav-link"
            activeClassName="active-link"
            onClick={() => setShow(false)}
          >
            Nossa Equipe
          </Link>
          <div className="nav-link contact-link">
            <Link to="/projects" className="btn" onClick={() => setShow(false)}>
              Entre para a Hut!
            </Link>
          </div>
        </div>
      </nav>
    )
  }
  
  export default Navbar
