Villagers disappearing

In bedrock realms villagers that u get disappear it's not really a consistent thing but once in a while they disappear it's really messing up the game,i haven't tried all of the villagers but i just know that the lectern villagers are disappearing and some other villager jobs too it's,u log out and log back in and they are gone,it's really annoying,it doesn't happen always but it's once in a while,it would help a lot if y'all fixed that.
