Something strange with url creating divisions

Hello people,

I have a site using the DIVI theme, but I would like to know if the problem that occurs to me is something from WP or my theme.
It turns out that regardless of the URL I navigate on my site, if I put / page / 02 the page loads like it was the same. This is not a new page.
It turns out this implies in my SEO because I have visitors clicking on

when you actually click

Would this be WP error?
