Note to Note link desapeared

Paul and whoever might be of assistance, 

Apparently when converting my database from 6 to 7 all my 'note to note' links disappeared. When I click at the bottom tab of the lower panel called 'links' in the B7 nothing shows up. I do have backup at the 6 version, though. Could you please advise how this can be fixed?

 Thank you.
