Deadly Map Bosses Doesn't Drop Any loot

hi , I playing pathfinder i have killed 3 deadly map bosses (maps: sealed vault , temportal storm , mantion in mist ) so far and bosses doesn't single loot. IMPORTANT : Please don't mistake these bosses with powerful map bosses. These bosses can drop divines of worth new lineage support gems but we can't get any drops with them. Also my friends can't any loot they also playing pathfinder poison builds.
