deluge shows wrong 'move completed to' folder

[lvm]

Deluge 1.3.6 is configured to move all competed torrents to /u/finished. A number of torrents are being downloaded. I select one, click on Options tab in the bottom pane and change 'Move completed to...' folder to /var/fin expecting it to change destination folder just fo this torrent. Text on the folder selection button changes from 'finished' to 'fin' but for all torrents, not just for this particular torrent - when I select another torrent folder remains 'fin'. When I click on this button deluge opens the 'correct' folder (/u/finished), so it seems to be a cosmetic issue, still it wont let me see the target folder. Actually I'd like to see a full path here, not just the the last folder in a path.
