FOSUserBundle形状看起来很奇怪

我刚刚在Symfony项目上配置并准备了FOSUserBundle。但是,当我尝试显示register视图时,它是这样的:

注册表表单(默认情况下)应如下所示:

所有我配置的都已打开 Documentation ,我不知道发生了什么事。

这是 RegistrationFormType。html。细枝 来自FOSUserBundle:

class RegistrationFormType extends AbstractType
    {
        ...

        /**
         * {@inheritdoc}
         */
        public function buildForm(FormBuilderInterface $builder, array $options)
        {
            $builder
                ->add('email', LegacyFormHelper::getType('Symfony\Component\Form\Extension\Core\Type\EmailType'), array('label' => 'form.email', 'translation_domain' => 'FOSUserBundle'))
                ->add('username', null, array('label' => 'form.username', 'translation_domain' => 'FOSUserBundle'))
                ->add('plainPassword', LegacyFormHelper::getType('Symfony\Component\Form\Extension\Core\Type\RepeatedType'), array(
                    'type' => LegacyFormHelper::getType('Symfony\Component\Form\Extension\Core\Type\PasswordType'),
                    'options' => array('translation_domain' => 'FOSUserBundle'),
                    'first_options' => array('label' => 'form.password'),
                    'second_options' => array('label' => 'form.password_confirmation'),
                    'invalid_message' => 'fos_user.password.mismatch',
                ))
            ;
        }
        ...
    }
