Incorrect links are created

After cloning from the main site to a secondary site in the same network of a WP multisite installation, some resources are not in the right folder. I give an example with a link:
https://menu.vegnavigator.it/wp-content/uploads/sites/11/sites/2/2025/04/copertina-risto-gray.jpg
In the link above, NS Cloner inserts sites/11/
In fact, the correct link is:: https://menu.vegnavigator.it/wp-content/uploads/sites/2/2025/04/copertina-risto-gray.jpg
I see that the folder has been created: wp-content/uploads/sites/11/2025/05
In any case, something is wrong.
