The registration key section on sa.php doesn't show active registration keys. I was able to fix this on my own version by changing the where line of the query in the getKeys function in dbl-class.php from
WHERE k.active = 1 AND k.time_add < ? AND comment != 'PW' ORDER BY time_add ASC"; to
WHERE k.active = 1 AND k.time_add < $time AND comment != 'PW' ORDER BY time_add ASC";
