How can Shortcodes load

I have imported Joomla Content articles (which contains some shortcodes from jDownloads) into Gridbox Blog.

However the shortcodes (from component jdownloads) do not load in front-end of Gridbox Blog page. How can I get the shortcodes to load and be viewable?

See sample Joomla Content article page with shortcodes viewable - https://pab.imapal.ca/
