-ISSUE- AngularMeteor, Meteor or Angular

Hello everyone thanks for reading. I have a question with Angular, AngularMeteor or Meteor.

Behaviors: When the result verCandidatos.postulados has only one value (see the first image) it never prints it the first time. If I refresh, or I give a second click then the values appear (like image 2) When, they are two values they always look perfect, there's never a problem Why is this behavior so strange and why only when it comes to a value?

Then my files.

html client

my-app / imports / ui / components / vacancies / seeCandidates / seeCandidates.html

<div ng-repeat="postulado in verCandidatos.postulados">
      {{postulado.candidato().nombre}} 
      {{postulado.candidato().apellidos}}
      {{postulado.candidato().sexo}}            
</div>

Next the images:

//////////// ISUE img1

//////////// ISUE img2

js in client

my-app / imports / ui \ components / vacancies / seeCandidates / verCandidates.js

imports ...

class VerCandidatos {
    constructor($scope, $reactive, $stateParams) {
        'ngInject';
        $reactive(this).attach($scope);
        this.vacanteId = $stateParams.vacanteId;
        this.subscribe('vacantes.candidatosOseleccionados', ()=> 
            [
                  {vacanteId: this.vacanteId}, 
                  {estado: 1}
            ]
        );
        this.helpers({
            postulados (){
                return Postulaciones.find();
            }
        });

    }
}

collection.js

my-app / imports / api / postulations / collection.js

imports...

export const Postulaciones = new Mongo.Collection('postulaciones');

Postulaciones.deny({...});

Postulaciones.helpers({
    candidato(){
        return Candidatos.findOne({_id: this.candidatoId});
  }  
});

publish.js:

my-app / imports / api / vacancies / server / publish.js

imports...

if (Meteor.isServer) {
    Meteor.publishComposite('vacantes.candidatosOseleccionados', function (vacanteId, estado) {
        const selector = {$and: [estado, vacanteId]};
            return {
                find: function () {
                    return Postulaciones.find(selector);
                },
                children: [
                    {
                        find: function (postulacion) {
                            return Candidatos.find({_id: postulacion.candidatoId}, {
                                fields: {
                                    nombre: 1,
                                    apellidos: 1,
                                    sexo: 1,
                                }
                            });
                        }
                    }
                ]
            };
    });
}

Any ideas? - Thanks,
