Omnifaces SelectItemsConverter does not reflect object values on screens

I'm using the selectOneMenu component with the omnifaces converter. When I save my object in the database it works fine, but when I restore the information, it does not reflect on the screen, that is, the selectOneMenu component is positioned in the first item or in the null item.

I've already confirmed with a log and a test inputText and the information loads correctly. I am using selectItemsConverter (I tried with SelectItemsIndexConverter also) of Omnifaces 1.8.3 (I tried version 1.10 too).

AutomacaoEmail.java

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

...

@ManyToOne(fetch = FetchType.EAGER)
private ModeloEmail modeloEmail;

...

@Override
public int hashCode() {
    int hash = 7;
    hash = 31 * hash + Objects.hashCode(this.id);
    return hash;
}

@Override
public boolean equals(Object obj) {
    if (obj == null) {
        return false;
    }
    if (getClass() != obj.getClass()) {
        return false;
    }
    final AutomacaoEmail other = (AutomacaoEmail) obj;
    if (!Objects.equals(this.id, other.id)) {
        return false;
    }
    return true;
}

@Override
public String toString() {
    return String.format("%s[id=%d]", getClass().getSimpleName(), getId());
}

loadFromDatabaseMethod ()

    List<ModeloEmail> modelosTemp = modeloEmailFacade.buscarTodos();
    SelectItemsBuilder selectItemsBuilder = new SelectItemsBuilder();
    if (modelosTemp != null) {
        for (ModeloEmail modeloEmail : modelosTemp) {
            selectItemsBuilder.add(modeloEmail, modeloEmail.getNome());
        }
        modelosEmails = selectItemsBuilder.buildList();
    }
