if you add any numbers at the end, for example /55/

site: https://recepty.mobi/postnye-retsepty.html

Expected result

So that when you open the site/menu-item-list-of-tags/55, a 404 error is displayed and not a duplicate.

Actual result

The page is accessible and a duplicate is opening

Additional comments

For some reason, this problem does not occur with all tag menu items. But when creating any new ones, a duplicate always appears.

For example, if you add /55/ https://recepty.mobi/novyj-god/salaty-k-novomu-godu.html for this page, then it will not have such a problem, but for some reason the page will still be accessible and will not return 404 error.
