Good morning.
If attach Meta Description and keywords to an article works well, but if I attach a category has to do is pick up the tags of the first article of that class, but not my position.

Can you solve?
New URL SEF: imagenes-eroticas/index.php
Old URL No SEF: index.php?option=com_content&id=4&limit=10&limitstart=0&task=blogcategory
Itemid: 25
Title: Imágenes Eróticas y Sensuales
Meta Descrition: Las mejores imágenes eróticas, sensuales, provocativas y picantes.
Meta Keywords: imágenes eróticas, erotismo, sensual, sensuales, provocativas, mujeres, chicas, desnudas, desnudos, tangas, cuerpos
Meta Content-Language: I do not anything.
Meta Robots: I do not anything.
Meta Googlebot: I do not anything.

Putting this and delete cached I get data from the first article.

Am I doing something wrong?

Thanks,
