Duplicate logins appearing in Identity safe

I have organised all my logins into folders under v5 but since I upgraded to v6 every time I use one it appears in a list. this list is getting very long and it defeats the purpose of having folders. If I delete from this list the log in also is deleted from the folder and I don't want to have to keep going to edit logins and moving them back into folders because they just reappear in this list as soon as I use them.  This did not happen in v5. How do I turn it off
