Hello, I've been having an issue with removing players from their assigned group.

Using /pex user parent remove and /pex user parent remove group gives me a confirmation in the console and in-game that the user has been removed, but instead of that, the player remains in that group, has that group's prefix, and can use every command assigned to that group.

I'm using PEX 2.0 on SpongeForge 1.8.9-1890-4.2.0-BETA-1508 with Minecraft Forge 1.8.9-11.15.1.1902. The only mods installed are Pixelmon 4.2.7 with sidemods, EssentialCmds 1.8.9-8.1.11, and PermissionsEx 2.0.

Here's the server log during startup: http://pastebin.com/Kx2ru7ER

Also, if there's anything wrong in there, please let me know, I'm new to server managing and I've still a lot to learn. Best Regards.
