Behavior Pack not working on Realms (but working well in a local world)

I created a Behavior Pack to remove spawn of specific mobs (zombie, witch, skeleton and others), allow to spiders, creepers and endermans to spawn.

 

Testing in a world created locally, this works very well. But in Realms is not working: zombies, witchs and skeletons stay spawning.

 

Only after 1.18.31 this problem appear, until the 1.18.30 versions worked properly. But is really strange that work in 1.18.31 local world, only in Realms not working.
