Stange problem with custom post type | General - All in One SEO Pack Pro Forum | Support | Semper Plugins

I have a strange problem in integration with a custom post type, the code i use to create custom post is this:

array( ‘labels’ => array( ‘name’ => __($this->label ), ‘singular_name’ => __( $this->postSlug ) ), ‘public’ => true, ‘has_archive’ => true, ‘show_ui’ => true, ‘show_in_menu’ => true, ‘show_in_nav_menus’ => true, ‘query_var’ => true, ‘supports’ => array( ‘title’, ‘editor’, ‘thumbnail’, ‘excerpt’, ‘page-attributes’ ), ) 

I have enabled the post in all in one settings page and a correctly see asociated title/keywords/description columns in mi custom post list page.

The problem is that if i open the post to edit it the seo fields are not filled like in list page. i can reedit them and save and the data is saved correctly but if a save the post without refill them the data are saved as blank.

So, when i open the post editing page the plugin doesn’t resume the plugin field values.

Some ideas, there is something missing in the post type declaration?

Thank you in advance.
