Hello,

1. Unfortunately, the single page comes from the “WooCommerce” plugin, so we can’t affect this.

2. In order to remove the “Review” tab, try to add this code to the functions.php file in your child theme.

if ( ! function_exists( 'wd_single_remove_reviews_tab' ) ) {

    function wd_single_remove_reviews_tab( $tabs ) {
        unset( $tabs['reviews'] );

        return $tabs;
    }

    add_filter( 'woocommerce_product_tabs', 'wd_single_remove_reviews_tab', 110 );
}

3. To remove icons from categories in the page title, try to use custom CSS in Theme Settings -> Custom CSS -> put this code in the field “Global Custom CSS”.

.page-title .category-nav-link img { 
  display: none; 
}

4. To remove categories from the page title, go to Theme Settings -> Product archive -> Page title -> find the “Categories in page title” field and disable it.
