Pale Garden biome is not spawning in pre-existing Realm.

Pale Garden biome is not spawning in pre-existing Realm. The Realm was already created before the biome update happened, and it said we updated it for the Pale Garden, however when we use the locate cheat/code- it gives us coordinates biome’s not there.
The creator of the realm is on PC, and the other members include: PlayStation 5, Nintendo Switch, and Xbox series X. We have all updated our consoles and our Minecraft games.
