Hidden no longer works with symfony update

Currently, I am updating the system running on the existing Symfony 2.3 (currently 3.0.9), and I am verifying the operation.

HiddenType is used for the function that when you select a value in the search form, only the data that is the status is displayed.

I changed from 'hidden' toHiddenType :: class in the Symfony update, but the feature doesn’t work and all the data is displayed. I am seeking advice.

Code

    {
        // brandsex
        $builder->add('brandSex', HiddenType::class, array(
            'required' => false,
        ));

        // flag
        $builder->add("brandDispFlg", HiddenType::class, array(

Usually I set hidden type like this, try, maybe it helps you:

$builder
     ->add('attributeName', TextType::class, [
        'label' => false,
        'attr'  => ['hidden' => 'hidden', 'value' => 'myHiddenValue']
