I think this relates to this problem.
It looks like you have additional content inside your meta tags, e.g.
<meta name="twitter:description" ng-metainfo="metaTwitterDescription" class="ng-isolate-scope" content="En los 10 años del PS3: realiza este quiz para demostrar que eres un fanático del PlayStation 3 ¿Puedes con el reto? compruébalo aquí.">
The ng-metainfo and class attributes are causing the content value to be missed by our crawler. Can you try removing those?
