Villagers and Iron Golems Disappearing/Despawning

My realm keeps deleting my villagers and golems. The village is well lit and secure. First to disappear were three master armorers and two master weaponsmiths, all in one building. Then, master priest and farmer in seperate buildings, and a total of three iron golems, excluding one that spawned naturally in a nearby village that also disappeared.

 

If it matters, all villagers are cured zombies.
