Description not showing

Hello, I installed and activated a Simple Blog Card.
Thank you for providing an awesome plugin.
I can’t use the plugin’s UI on Block Editor due to using another editor plugin.
Though I wrote a shortcode, “[simpleblogcard url=”https:// my URL “]” for a custom post type article on the page, it works but doesn’t show the description of the article.
How can I show the description?
Please let me know if I miss something.
