You did not explain, which folders are duplicate.
Does "duplicate" mean, that they have the some content or just the same 
name? If copy one message into one folder, is it accessable through the 
other one?

Well, you mean "Sent" and "INBOX.Sent", which latter is a mailbox named 
"Sent" as subfolder of INBOX, then they are not duplicates, but have the 
same name. Eventually, your mail client strips the leading "INBOX" for 
convience for the user. Possibly, you had mailbox prefix configured in 
your setup ago, which hid all mailboxes except "INBOX" and below. Perhaps 
you have entries in your subscriptions files, which are no longer 
available, because of the other setup.
