Reviews not showing for particular categories

Hi

I am using shortcode to show reviews from particular categories but its showing always all reviews
echo $term->name;
echo do_shortcode(“[wc_photo_reviews_shortcode comments_per_page=’3′ cols=’3′ cols_mobile=’1′ use_single_product=’on’ cols_gap=” products=” grid_bg_color=” grid_item_bg_color=” grid_item_border_color=” text_color=” star_color=” verified_badge_color=” product_cat='”.$term->name.”‘ order=” orderby=” comment_date_gmt” show_product=’on’ filter=’on’ pagination=’on’ reviews_per_page=” pagination_ajax=’on’ filter_default_image=’off’ filter_default_verified=’off’ filter_default_rating=” pagination_position=”conditional_tag=” custom_css=” ratings=” mobile=” style=’masonry’ masonry_popup=’review’ enable_box_shadow=” full_screen_mobile=’on’ overall_rating=’off’ rating_count=’off’ only_images=’off’ image_popup=’below_thumb’]”);

Thanks
