I studied More about the new versión mob spawning problem. And if you already have a world. This problem Will apear. Also Mobs like guardians in a ocean temple Will not spawn. Only spawn Illagers, EnderGuardians, and not hostile Mobs. This bug ruins my Mob farm. And The only way I find its ti create a new world. And even in the new gane, the Mobs spawn low in surface. Un caves are low but not to much.
