laravel not setting session data from first time - php

Question

Alright so I got this locale system with a middleware, the issue is that when I enter language "hu"it doesnt set it the first time, it usualy works only the 2nd time I do it...
web.php
Route::get('set_language/{locale}', function ($locale) {
Session::forget('my_locale');
session(['my_locale' => $locale]);
return Redirect::back();
});
Language.php inside HTTP/middleware
<?php namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Illuminate\Foundation\Application;
class Language {
public function __construct(Application $app, Request $request) {
$this->app = $app;
$this->request = $request;
}
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
$this->app->setLocale(session('my_locale', config('app.locale')));
return $next($request);
}
}
And of course I added it inside my Kernel.php on couple of spots that seemed correct
namespace App\Http;
use Illuminate\Foundation\Http\Kernel as HttpKernel;
class Kernel extends HttpKernel
{
/**

*
* These middleware are run during every request to your application.
*
* #var array

\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
\App\Http\Middleware\TrimStrings::class,

\App\Http\Middleware\Language::class,
];

],
'api' => [
'throttle:60,1',

],
];
/**

*

*
* #var array
*/
protected $routeMiddleware = [
'auth' => \App\Http\Middleware\Authenticate::class,

'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
];
/**

*

*

protected $middlewarePriority = [
\Illuminate\Session\Middleware\StartSession::class,
\App\Http\Middleware\Language::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,

}
EDIT:
I forgot to mention, but in the config/app.php I've set it this way
'locale' => 'rs',
'locales' => ['rs', 'hu'],
'fallback_locale' => 'rs',
'available_locale' => ['rs', 'hu'],
So now If I got to the localhost:8000/set_language/rs it works, but if I do localhost:8000/set_language/hu it works only after I do it twice.
I tried dumping the session key my_locale and it stays as "rs" until I do the set_language/hu twice
So how I do it?
Go to: localhost:8000/set_language/hu
Go again to: localhost:8000/set_language/hu
Now it works...
Why isnt it being set the first time around?
Just to add up, if you are testing this, try setting your locale to RS first and then try to set it to HU
