Plugin Help Tekkit Classic Pex Error

Every time I try to start the server after making adjustments to Pex I get a bunch of [Severe] errors in the console below. I'm sure it has something to do with the permissions.yml so I will attach that as well for troubleshooting there. I haven't edited any of that by hand I've only used console commands to add groups and set a default. Thanks in advance for any recommendations!
