if you're using the newest PEQ DB (rev 245) you do one of the following queries: 
TRUNCATE TABLE respawn_times; 
DELETE FROM respawn_times; 
 
and it will remove everything from there and therefore be spawnable, if you're using an older DB you can do  
UPDATE spawn2 SET timeleft = 0; 
 
and also check if they're even in the spawn tables as someone else said
