Repeater field images to Gallery Image

I have a submission form on my website, I try to get images from the repeater field to gallery images and it’s work. I have just followed John Huebner answer here:
https://support.advancedcustomfields.com/forums/topic/repeater-field-images-to-woocommerce-gallery/

But, the problem is, when I tried to edit the gallery image, I added a new image, but the new image wasn’t updated. Only the image of the form submission is there.

Any idea how to get this done?

// Set Repeater Image as Gallery Images
function my_acf_save_post($post_id) {
    $repeater = 'preview_images_row';
    $subfield = 'preview_images_file';

    // using get_post_meta because that way we're sure to get the image ID
    $count = intval(get_post_meta($post_id, $repeater, true));
    $images = array();
    for ($i=0; $i<$count; $i++) {
        $field = $repeater.'_'.$i.'_'.$subfield;
        $images[] = intval(get_post_meta($post_id, $field, true));
    }
    update_post_meta($post_id, 'preview_images', $images);
}
add_action('acf/save_post', 'my_acf_save_post', 20); // priority of 20 so it runs after ACF
