There are a few errors with some of the natural attacks with monsters in Bestiary 3
The Demon (Coluxus) has 2 slams (1d4) that are missing in PCGen http://paizo.com/pathfinderRPG/prd/bestiary3/demon.html#demon,-coloxus
The Kyton (Eremite) should have 2 claw attacks and two wing attacks, but only has one of each in PCGen. (Incidentally, the wing attacks are secondary natural attacks, so they have a -5 penalty to attack and get half the damage bonus from str.)

PCGen lists a single "Slams" attack for the tophet, but there are two: http://paizo.com/pathfinderRPG/prd/bestiary3/tophet.html#tophet
The whole lot needs to migrate to the new natural attack system, but shudder that is a big project.
