laravel download response filename not changing

Question

I am using laravel and trying to download a file and change the filename. The documentation tells me that I can use the second argument as the new filename, but the filename won't change to "testdownload.zip" somehow. What am I doing wrong?

https://laravel.com/docs/5.8/responses#file-downloads

    // routes
    Route::group(['middleware' => ['web']], function()
    {
        Route::group(['namespace' => 'App\Http\Controllers'], function()
        {
            Route::group(['middleware' => ['role:root|admin|store|user']], 
function()
            {
                // download purchase
                Route::get('dashboard/order/downloadfile', [
                    'as'    => 'order-download',
                    'uses'  => 'Post\PostController@download'
                ]);
            });
        }
    }

    // method in Controller
    public function download(Request $request)
    {
        return response()->download(storage_path('app/lorem-ipsum-shop-1.zip'), 'testdownload.zip', ['Content-Type: application/zip']);
    }

When I do dd(response()->download(storage_path('app/lorem-ipsum-shop-1.zip'), 'testdownload.zip', ['Content-Type: application/zip'])) the following is returned (could it be the perms / permissions 0100666? I am on Windows):

Always clear your cache... I think it stores the filename before the renaming.
