Villagers are not spawning and chamber of trials doesn't spawn monsters

Hey 

I've recently opened my minecraft world into realms on bedrock edition, and it appears to be broken. Every single village I came across is empty, zombie villagers disappear after curing and trial chamber is not spawning any mobs. I haven't seen any dungeon at the moment so I can't confirm if it's only chamber problem or all spawners issue. I've read the post found somewhere here MC-231147and I know the case is reopened MC-153904but there was no information about chambers and also I'm lacking an option to enable npc in world settings if it's here. I'm playing on normal difficulty and without cheats mode on so I can get achievements. There are no mods or resource packs installed. Problem is making my game a little sad and boring especially that I pay for subscription of realms and it's not working properly does anybody else got similar problem or knows how to solve it? Before I've opened my world to realms everything was working just fine. 
hoping to hear from you
