GriefPrevetions Not Working

I have a sponge server with GP, LuckPerms and Pixelmon.
When i join i try to claim but i can’t, i add the nucleus group at my user, i can do all commands but GP does not work, somebody can tell me why?
(sorry for bad english btw)

Could you send us a log of the server using a service like You can find your server logs in the following folder.


That will give us a idea of what is going on.
