Emails sent count doesn't work

I see:
0 emails sent to 0 recipients

Even though the forward_log table has two rows

47  	SENT  	1142429782
47 	SENT 	1144150375

Is my db schema outdated or something? It doesn't include recipient email so I'm not surprised it says "0 recipients".

CREATE TABLE forward_log (
  nid int(10) unsigned NOT NULL default '0',
  type varchar(8) NOT NULL default '',
  timestamp int(11) NOT NULL default '0',
  KEY (nid)
) TYPE=MyISAM
