How to dynamically modify forms using FormEvents on multiple fields in Symfony 5.4

Question

So I have a form on which I want to be able to modify multiple fields, to make it short I have followed the documentation regarding FormEvents to add an event listener on my category field.

And it does work, when I select a category the product categories(prodcat) of the category I've chosen shows up.

However I also have in my form a Type of product(top) field and I want to be able to choose a product category and have the type of products(top) related to the product category(prodcat), but when I add another PRE_SET_DATA AND POST_SUBMIT To my form it does not work. I can read off category but not prodcat.

Is there a way to listen to multiple fields ?

I did test them seperatly and they both work, but when they are together it only works for category.

Here is my form type :

    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('category', EntityType::class,[
                'class' => Category::class,
                'choice_label' => 'cat_name'
            ])
            
            ->add('filter', EntityType::class,[
                'class' => Filter::class,
                'choice_label' => 'name'
            ])
            ->add('name', TextType::class,[
                'required' => true,
                'label' => 'Nom de produit',
                'constraints'=>[
                    new Length([
                    'min' => 3,
                    'max'=> 55,
                    'minMessage' => "Le nom de catégorie doit avoir un minimum de {{ limit }} caractères.",
                    'maxMessage' => "Le nom de catégorie ne doit pas faire plus de {{ limit }} caractéres."
                    ])
                ]
            ])
            ->add('image', FileType::class,[
                'mapped'=> false,
                'required' => false,
                'constraints' => [
                    new File([
                        'mimeTypes' => [
                            'image/jpg',
                            'image/png',
                            'image/jpeg',
                            'image/bmp',
                            'image/webp',
                            'image/svg+xml',
                            'image/gif',
                        ],
                        'mimeTypesMessage'=>"Ce fichier ({{ type }}) n'est pas au format valide.
                        Veuillez mettre un fichier de type : .jpeg, .png, .gif, .svg, .jpg, .webp, .bmp",
                    ])
                ],
            ])
            ->add('state', ChoiceType::class,[
                'label' => 'état',
                'choices' => [
                    'Neuf' => 'Neuf',
                    'Occasion' => 'Occasion',

                ]
            ])
            ->add('description')

If there is any additional information needed, feel free to ask. Thank you for reading.

I tried to modify multiple fields in order to have everything filtered through what the user has selected, alas only one field works correctly.
