The shortcode shows similar dates

Hi,

I am using the shopscape plugin by boldthemes. I have listed my blogs using grid in a regular page. Now, I would like to add last modified date into the blog grid. For that, I need to put the shortcode in shopscape.php file, that is template file. I have already added the shortcode over there.

The problem here is each blog post is showing the same date. Why? How to solve that?
