Duplicated password validation messages ONLY IF new password is 1 char long

Question

My problem is password validation message appears twice in Registration and Change Password forms. As most posts/solutions points out "groups", how do I implement it into my code below? I tried to implement other solved examples as shown below but I cannot get it working. Maybe because I never worked FOSUserBundle before.

• FOSUserBundle - Validation for username, password or email fields
• Duplicated errors for constraints when using several validation groups
• Symfony2 FOSUserBundle extending registration form causes duplicate email to validate
• validating fosuserbundle registration form
• Validation of a form - I'm getting the labels two times

myapp/app/config/config.yml

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: WebsiteBundle\Entity\User
    model_manager_name: websitemanager
    registration:
        form:
            type: website_user_registration
    change_password:
        form:
            type: fos_user_change_password
            validation_groups:  [ChangePassword, Default]

WebsiteBundle/Resources/translations/validators.en.yml

fos_user:
    password:
        short: "[-Inf,Inf]The password must contain at least 8 characters"

    {
        parent::buildForm($builder, $options);

        $builder->add(
            'terms',
            'checkbox',
            [
                'label' => 'Older than 18',
                'constraints' => [
                    new IsTrue([
                        'message' => 'Are you older than 18?',
                    ]),

                'mapped' => false,
            ]

    }

Have a look at the group_sequence feature for validations.

# src/AppBundle/Resources/config/validation.yml
AppBundle\Entity\User:
    group_sequence:
        - User
        - Strict
    getters:
        passwordLegal:
            - 'IsTrue':
                message: 'The password cannot match your username'
                groups: [Strict]
    properties:
        username:
            - NotBlank: ~
        password:
            - NotBlank: ~

In this example, it will first validate all constraints in the group User (which is the same as the Default group). Only if all constraints in that group are valid, the second group, Strict, will be validated.

This is taken straight of the Symfony documentation at http://symfony.com/doc/current/book/validation.html#group-sequence

However personally I could never get this feature to work.
