When in online mode, Frequent Contacts seems to be updating its list when you send an email to someone who's email address is not on the FC's list. But that's not the case when in Caching mode. It does nothing. It didn't add the recipient's address to Frequent Contacts. Even if you send 2 or 3 emails to that same recipient that day. Is this normal? Is this by design?

If yes, then do you have to be in online mode if you want the recipient's address to be automatically listed in Frequent Contacts? Then when you switch to caching mode, the updated list in Frequent contacts will be downloaded to your computer; cached Frequent Contacts will then be synchronized to your online frequent contacts(from the server)... Is this how it works?
