Need help with Elementor builder

I’m redesigning the website [ redundant link deleted ], which was previously created by someone else. The website pages are created using the Elementor builder, and when editing any page on the site using Elementor, it automatically redirects to /product/mnogomestnaya-sekcziya.
You can go to any page on the site and try editing it using Elementor in the control panel at the top, and it will automatically redirect to the page.
/product/mnogomestnaya-sekcziya Also, all the pages on the site, except the main one, are similar to this page /product/mnogomestnaya-sekcziya, i.e.
I added blocks and content to it using Elementor, and it was automatically applied to all pages. I’ve built websites with Elementor before, but this is the first time I’ve encountered this glitch.
I’ve reviewed all the settings and don’t understand what’s wrong… I’ve posted screenshots of this situation at the Yandex Disk link.

Maybe someone has already encountered something similar and understands what the problem is and how to fix it?
