Bing shows that some non existent urls that seems to belongs to other cloudlare sites

Hi,
Bing shows that some non existent urls are found on verona.com and travelnorvegia.com sites. From urls it seems they belongs to other cloudflare sites. This is happening from september.
Example:
Bing Site Explorer on travelnorvegia.com shows:
https://travelnorvegia.com/intouch-sf/3-day-joshua-tree-core-and-yoga-retreat-in-california
this url does not exist on travelnorvegia.com and seem to belongs to:
https://www.bookyogaretreats.com/intouch-sf/3-day-joshua-tree-core-and-yoga-retreat-in-california.
From “whois bookyogaretreats.com” I discovered that this site is on cloudflare too. I think something wrong happened to cloudflare at the end of august or in september.

Does someone have the same issue?

Thanks in advance
Paolo Groppo
