Products are not displayed in woocommerce product filter, what should I do?

Question

WordPress

Good day, this is the problem I faced:
There is an online store site with woocommerce plugin and woocommerce product filter installed. I added products, but out of 30 products only 6 are displayed. I would be grateful for your advice.
I display the products on the page with the shortcode: [prdctfltr_sc_products]
The site also contains the following plugins: All-in-One WP Migration, Contact Form 7, Custom Content Shortcode, Custom Related Products for WooCommerce, Duplicate Post, File Manager, MailChimp for WordPress, Max Mega Menu, Minerva KB, Popup Maker, SiteOrigin Widgets by CodeLights, Slider Revolution, TablePress, TablePress Extension: Responsive Tables, Ultimate Addons for Visual Composer, UpSolution Header Builder, WooCommerce,
WooCommerce Product Filter, WPBakery Visual Composer, Yoast SEO
