Page display error

Hello everyone!

The essence of my problem is as follows. On the site, I created a page called “domain.com/management” (first level). Everything worked fine. Then I made another page with the same label, but at the next level: “domain.com/encyclopaedia/management” (second level). In theory, since the addresses of the pages are different, everything should work fine. Nevertheless, now, when viewing the first page in a browser, the following picture emerges: firstly, the content of the second-level page is shown, and then the first.

After disabling the Elementor plugin, the problem disappears and the first level page is displayed by itself – without unnecessary inserts. Hence, the failure is most likely at the level of this plugin.

Can you please tell me how you can solve the problem?

Thank you!
