Question Enjin plugin issue.

So i created my server website with enjin but there is a problem with the commands that run after the buying an item.

I want to set the buyers group to a specific rank but it doesn't work.
I tried setting any other command to see if it works and it does.

I am using group manager and the command i use is /manuadd {name} group

Nevermind i found the issue but i still need an answer. So the command /manuadd {name} group is ran in my server's default world and not in the wanted one and that leads to my other thread https://bukkit.org/threads/groupmanager-issue.470062/#post-3574003. So if anyone know how to change a player's rank in a different world please tell me. When i do /manuadd <player> group Arena i get an error message
