Im trying to make a modpack with zombie and parasites but the Hordes wont just spawn. Im on the 1.20.1 and i tried everything like deleting hordes and reinstalled it and also looking into the config but not even on day 0 they want to spawn. I dont even have the settings on to manually spawn them.
Here are my config settings:

["Horde Event"]
