After poking around the theme it appears that the sticky posts query parameter in featured.php is not part of the function that is used to build the list of featured posts to be excluded from the post list.
Here is the function that builds the list of featured posts that’s used in the exclude posts function:
function alx_get_featured_post_ids() {
$args = array(
'category' => ot_get_option('featured-category'),
'numberposts' => ot_get_option('featured-posts-count')
);
$posts = get_posts($args);
if ( !$posts ) return false;
foreach ( $posts as $post )
$ids[] = $post->ID;
return $ids;
}
I’m only guessing that, since the sticky posts parameter is missing, it defaults to 1 (ignore). What you might try is copying that function to your child theme functions.php and adding the sticky posts parameter to see if it will then include them in the featured posts:
function alx_get_featured_post_ids() {
$args = array(
'ignore_sticky_posts' => 0,
'category' => ot_get_option('featured-category'),
'numberposts' => ot_get_option('featured-posts-count')
);
$posts = get_posts($args);
if ( !$posts ) return false;
foreach ( $posts as $post )
$ids[] = $post->ID;
return $ids;
}
