do_shortcode doesnt replace certain shortcodes // used within plugin

Hello,

I’m using a plugin to keep portfolio entries between two wordpress-websites in sync (plugin is called wordpress-api-content-sync).
Particularly, the plugin posts the post_content data of a portfolio entry to another wordpress-site.

I would like to parse the shortcodes and convert it to html before posting (as it contains ALB shortcodes).
Instead of sending the “post_content” data of an entry, I tried to convert it with do_shortcode()

$post_info = get_post( $post_id );
$data = array(
[...]
                'content'           => do_shortcode($post_info->post_content),
[...]

However, this doesnt seem to work, as the data still contains shortcodes (like [av_slideshow_full]). Some shortcodes like [av_slide_full…] are just removed.

How can I parse the shortcodes? Any support would be greatly appreciated.

Thanks in advance
Patrick
