Prepending place page titles

Hi Guys,

I am using the following function to append “Reviews for ” to each businesses place page, but for some reason the function fails to affect two of the 10 sample listings I added to my Dir.

Echoing post type confirms that the unaffected pages are using the same custom post type as other place pages the function works fine on:

/* append “review ” to place page titles */
add_filter( ‘the_title’, ‘change_title’, 10, 2 );
function change_title( $title, $postid ) {
global $post;
$text = ‘Reviews for ‘;

if( get_post_type() == gd_place && $title == $post->post_title ){

return $text . $title;
}
else {

return $title;
}
}

Any ideas what could be the cause of this?
