Duplicate foreach

Hello everybody!
I've been having a problem for a few days, and I can't solve it.
Can anyone help me?

I have a filter, where I am doing a join, but I am getting duplicate results.

$modelApp = new \App\Models\App();
$menuPai = new \StdClass();
$request->menuPai = $modelApp->select('apps.*, appmenus.menuAdmin submenu')
->join('appmenus', 'appmenus.app_url_admin = apps.urlAdmin', 'left')
->findAll();
return $request;

The Email main menu should appear once, and below it show the Enviar and Criar submenus.

However, the Email main menu is repeating.
