New media uploader hides past attachments in wysiwyg [closed]

Question

I am using the Advanced Custom Fields plugin to add a WYSIWYG field that I have uploaded an image gallery into. After the new Media Uploader WP update I can no longer edit the existing galleries as they do not show up in the WYSIWYG, but the images are still attached to the post. If I add new images they show up on the front end but I can not control the order and can not delete them from the post. Is there a way to reconnect the editor to the existing images so I can edit them from the post?

Here is the code I'm using to retrieve the images from the post:

$args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_status' => null, 'post_parent' => $post->ID, 'orderby' => 'menu_order', 'order' => 'ASC', ); 
$attachments = get_posts($args);
if ($attachments) {
    foreach ( $attachments as $attachment ) {
    echo '<li>';
    echo wp_get_attachment_image($attachment->ID, 'large');
    echo '</li>';     }
}

Advanced Custom Fields made an update that fixed the problem. Still not sure what caused it, but at least it is functioning again. Thanks for your help.
