PerWorldInventory not working for 2 out of 4 worlds

For some reason, PerWorldInventory works for the lobby and creative worlds, (it's one server) yet when joining the PVP world (survival) it shares the inventory with the Survival world (also survival)

I have no idea how to fix this, as I don't think the problem is in the PerWorldInventory config.

Any Ideas?

thanks,

I'm not using multiverse-inventories, but here is my PWI config:

Not that I know of. Here are a list of the plugins I am using currently:

Broadcaster

Essentials

GroupManager

Headdrops

Multiverse-core

Multiverse-portals

Perworldinventory

Plotsquared

Vault

Worldedit

Worldguard

I do not know what the problem was, but I fixed it by creating a new group for the survival world. Somehow worked.
