Same review for every item

We are using the gdrts_stars_rating shortcode to display a rating for each item on a page with a list of items (these are custom post types, under the “posts” entity) identified with the “id” value for each individual item in the list. But the same review is displayed for every item in the list. Say it is a list of restaurants on the page, they all show 4 stars, and if you change the rating for one of them, when you reload the page, they all show that new rating.
