Plugin Help PermissionsEX doesn't work

This is the situation: I have set -modifyworld.* to world and lobby, but people in "default" group can still break and place blocks in "world" and "lobby". Is there any problem on my permission?

N0, you haven't. You have added the node modifyworld.* to them, which appears as the yml list item of "- modifyworld.*" , which gives them the ability to bypass checks and ability to break things, which is why they are .. able to break things.

You want to add the node -modifyworld.* which is a negative node to negate the held node permissions.
