Error in Google analytics

Hello,
Looking into Google analytics, I noticed a series of pages in error.
They concern the CBConnect plugin.
Do you know what this is?
Have you seen this problem?
CBConnect works fine, no problem.
Thanks

For exemple

---

Explorer as Google
Here is how Googlebot fetches the page.

Google is trying to index the Facebook CB Connect registration page. Google crawls every URL it can possibly find and that URL is exposed, because it's a part of CB Connect and used for the connect buttons. Nothing you can do about it except maybe add an exclusion to your Google account so it won't be crawled or try blocking the directory with your robots file.

hello,
What is strange is that the / component / is already blocked in robots.txt!
I'll add exclusions in Google.
thank you
