Admin is not getting logout in Multi Authentication - php

Question

I am trying to make Multi Authentication for Admin and User.
User is getting logged in and logged out without any problem.
But Admin is logged in but not getting logged out. Do I require double
logout function or I am making up mistake.
AdminLoginController.php
<?php
namespace App\Http\Controllers\Auth;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
class AdminLoginController extends Controller
{
public function __construct()
{
$this->middleware('guest:admin', ['except' => 'logout']);
}
public function showLoginForm(){
return view('auth.admin-login');
}
public function login(Request $request)
{
//Validate the form data
$this->validate($request,[
'email' => 'required|email',
'password' => 'required|min:6'
]);
//Attempt to log th user in
if (Auth::guard('admin')->attempt(['email' => $request->email,'password' => $request->password],$request->remember)){
//if successful, then redirects to their intended location
return redirect()->intended(route('admin.dashboard'));
}
// if unsuccessful, then redirect back to thee login with the form data
return redirect()->back()->withInput($request->only('email','remember'));
}
}
Login Controller.php
<?php
namespace App\Http\Controllers\Auth;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Support\Facades\Auth;
class LoginController extends Controller
{
use AuthenticatesUsers;
protected $redirectTo = '/';
public function __construct()
{
$this->middleware('guest')->except('logout');
}
public function logout(Request $request) {
Auth::logout();
return redirect('/');
}
}
