Why CI PSR4 do not accept more than one module?

Hi all I was taking a little bit of a look and found that in CI PSR4 autoloader, it does not work for more than two module autoloading as follows:

PHP Code:

public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
          'Config'      => APPPATH . 'Config',
//Here if both, only one work why??!!
          'Admin\Editor'  => ROOTPATH . 'Admin/Editor',//this is working
          'Admin\User' => ROOTPATH . 'Admin/User',//not is not working
    ]; 


Above there are two namespaced modules and all work fine except I have to switch off one
like

PHP Code:

public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
          'Config'      => APPPATH . 'Config',
              // 'Admin\Editor' => ROOTPATH . 'Admin/Editor',
   'Admin\User' => ROOTPATH . 'Admin/User',//This will work because first one is off

    ]; 


and

PHP Code:

public $psr4 = [
        APP_NAMESPACE => APPPATH, // For custom app namespace
          'Config'      => APPPATH . 'Config',
          'Admin\Editor' => ROOTPATH . 'Admin/Editor',//This will work fine because the second one is off
 // 'Admin\User' => ROOTPATH . 'Admin/User',

    ]; 


Why this or is there any priority like (route priority) should I use?

Thank @kenjis Every things are now okay but I don't know why if I use

PHP Code:

<?php namespace Foo\User\Config;

$routes->group('user', ['namespace' => 'Foo\User\Controllers'], static function ($routes) {
    
      //$routes->match(['get', 'post'],'index', 'userHome::index');  does not work
    
    $routes->get('index', [\Foo\User\Controllers\userHome::class, 'index']); //This style work

 
}); 


I have used your fully qualified root namespace example and now about ten modules work fine !!!!

It is weird. The following code also works.

PHP Code:

<?php

namespace Foo\User\Config;

use CodeIgniter\Router\RouteCollection;

/**
* @var RouteCollection $routes
*/
$routes->group('user', ['namespace' => 'Foo\User\Controllers'], static function ($routes) {
    $routes->match(['get', 'post'], 'index', 'Home::index');
}); 


Code:

$ php spark routes
