Essential Content Types Portfolio image links

I created a standalone home/landing page that links via an 'Enter' button to another standalone page that incorporates [portfolio...] shortcode, rather than use the Gridalicious Pro theme's default Featured Grid Content layout. I want the displayed portfolio images to link to the relevant POST when clicked, but they will only link to the featured image itself. How can I do this? Same result if using [featured_content...] shortcode. Appreciate your assistance.
