LuckPerms & Multiverse/FAWE

I use Multiverse. Players should be able to teleport to other worlds but not use any other Multiverse commands. So I made a group (jumpers) with the permission "multiverse" set to false and the permission "multiverse.teleport" set to true. That's what I read all across the internet and it doesn't work. Even just allowing "multiverse.teleport doesn't work. Only when I allow "multiverse", players can teleport.

I can't even begin to start working on specific rules that way.

My goal is to allow "/mv tp" for all players in the group "jumpers" but only in overworlds to overworlds. This is my first time using LuckPerms, so maybe I'm understanding something wrongly.
Also I have a similar problem with FAWE. Players can use "//wand, but can't use for example "//set stone" due to region restrictions. I (operator) can do that with no problems. I'm clueless and Google isn't helping, so I'm hoping for help here.
