Featured Image not showing in Coursepro

Hi, I used the shortcodes;
[course show="title,summary,cost,button" course_id="27"]

[course show="title,summary,cost,button" course_id="124"]

[course show="title,summary,cost,button" course_id="184"]
Bbut not showing the featured image on the Post Home Page of my course, how can I solve this?
