URL indexed with ?page=89498

[HypNoTeeZz]

Hello,

I have a site in contao 4.13.*

My urls on Google are indexed correctly.
However, the same pages are indexed but with ?page=53 at the end.

Ex :

www.mondomaine.fr/contact.html
and
www.mondomaine.fr/contact.html?page=4565465
Where
www.mondomaine.fr/contact.html?page=454

What to do ?

Hi,

Can it be that the page was created with October CMS and not with Contao?
