All in One SEO Pack wrong output

hello i need help with this.

im also using theme
atahualpa Versión 3.7.12
All in One SEO Pack 2.0.2
WordPress 3.5.1.


this is a post for a site:
http://diganmecomo.com/como-liberar-...lular-android/

type the url on Google, and you can see this:

"Cómo liberar espacio en un celular Android - Política de Privacidad"

on the all in one settings i have this:
Post Title Format: post_title

so it means it should only output the post title, but it doesnt, it reads something extra like politica de privacidad which is the title of one of the pages of the site, which is not related to the specific post.



i also cannot keep testing settings on both the plugin and the theme, like switching to the default wordpress theme or deactivating the plugin to see if thats the issue, because google doesnt update the title and description instantly, and they also dont tell you when are they going to index a post.

anyone having the same issue please help.
