Instead of 404 errors, it shows "element not found" bitrix?

Question

1C-Bitrix

If you remove the page activity, then instead of an error on the page url, it gives the page and highlights in red "element not found", and it will probably be correct to issue a 404 error when inactive, otherwise the title and description are duplicated. How can this be corrected?
I don't know much about bitrix
