The documentation says that if you clone a HUB site, then all the pages are also cloned AND should be named "originalpage 1":

That is not what is happening. The cloned pages have EXACTLY the same name as the original pages. That is dangerously confusing, as it would be easy to edit or even delete the wrong page.

All the cloned stuff also gets dumped right into the root folder. It would be way better if all cloned materials got put into a dedicated folder automatically.
