post attributes not saving post order

[shadiadi]

the post attributes are not saving post order once the number of posts added has reached the amount to display in reading settings.

I set my posts to display post attributes order.

add_action( 'admin_init', 'posts_order_wpse_91866' );

function posts_order_wpse_91866() 
{
    add_post_type_support( 'post', 'page-attributes' );
}

They were all saving fine and showing in order until I got to my 11th post. My reading settings are set to 10 per page. All of a sudden my posts orders had all been reset to zero. Now trying to add the order again to the posts is not even saving the order amount when republished. It seems to be a bug in the Rest API somewhere because it was working until it got to my reading settings display limit.
