Valor do Enum não passa para a Label | Spring MVC I: Criando aplicações web

Olá pessoal, estou tentando aplicar o valor que esta o Enum para o <label> como é feito na aula, porem ele não esta atribuindo um valor. Podem ajudar? Tem alguns campos diferentes para usar aqui num trabalho pessoal, mas não foge do conteúdo da aula:

        <div>

            <textarea rows="10" cols="20" name="description"></textarea>
        </div>
        <br>
        <c:forEach items="${types}" var="pricingType" varStatus="status">
            <div >
                <label>${pricingType }</label>
                <input type="text" name="prices[${status.index}].pricing">
