Log out now unusually auto logging back in

So my constructor for auth0 is basically the same as the React SPA guide.

constructor() {
        let hostname = window.location.hostname;

        this.auth0 = new auth0.WebAuth({
            domain: process.env.AUTH0_DOMAIN,
            clientID: process.env.AUTH0_CLIENT_ID,
            redirectUri: `${window.location.protocol}//${hostname}/callback`,
            audience: `${process.env.AUTH0_AUDIENCE}`,
            responseType: 'token id_token',
            scope: 'openid profile app_metadata roles'
        });

        this.login = this.login.bind(this);
        this.logout = this.logout.bind(this);
        this.handleAuthentication = this.handleAuthentication.bind(this);
        this.isAuthenticated = this.isAuthenticated.bind(this);
        this.userHasScopes = this.userHasScopes.bind(this);
    }
  
    login() {
        this.auth0.authorize();
    }
  
    handleAuthentication() {
        this.auth0.parseHash((err, authResult) => {
            if (authResult && authResult.accessToken && authResult.idToken) {
                this.setSession(authResult);
                history.replace('/');
            } 
            else if (err) {
                console.log(err);
                alert(`Error: ${err.error}. Check the console for further details.`);
            }
        });
    }
