No IDs Generated in HTML for Custom Post Types

I created custom post types via CPT UI plugin. On a page with a grid of profile images, each image is from a post. When I view the HTML generated, these posts do not have a unique ID; they all have identical IDs and classes. How do I fix this?

I need the IDs to target posts individually with jQuery.

Thanks for taking the time to look at this!
