display repeatable field

Hi, I am using facetwp to create a template.
I can display the title and other fields but I am NOT able to do it with a repeatable field.
In that case, I get the following output on the screen "ACF".

Could you please tell me if something is wrong with my code?

<?php
 $descripciones_todas = rwmb_meta( 'descripcion' );
     foreach ( $descripciones_todas as $descripcion_contenido ) {
         echo $descripcion_contenido['descripcion'];
     }
 ?>

Thanks!
