No coursepress pro id found

Hi, I do not find the ID of a course. When I edit a course my address looks like this:
/wp-admin/post.php?post=28287&action=edit&lang=de

There is no special course ID. If I am using the post ID (in this case 28287) the shortcode doesn't work correctly. No title and details link not working.
I tried this: [course show="title,summary,cost,button" course_id="28287"]
and getting this (see attachment)

kind regards R.
