Trouble with all GUIs on my server.

Hey so recently I installed the Duels Plugin because it looked really cool. I set everything up and then when the GUI popped up where you could select your kit, it didn't work. When I clicked on the icon (strength pot) it just got picked up like any other item that would be in your inventory when you click it. I can move it into my inventory place it back. It does not work. I had the same trouble earlier when I installed the plugin HeadHunter. The sellhead sign was a GUI and when I clicked it the same things happened I could move the icons. It is not just because I am OP I have alts to test on and it was the same for all of them. I am running quite a few plugins: FactionsOne EssentialsX FactionsTop EssentialsChatColor HeavySpleef ManageGroups Vault FactionsFly(for FactionsOne) CombatLog+ CommandCooldowns StackableItems WorldBorder WILDTP MultiWorld and FoodandToolsX

Could anybody help me?

 

The same thing is happening to me! When you click on the gui items, does it send a mighty long message in your console too?

 

@HeroJackPvP I'm guessing the plugin is out of date or needs to be updated. Is your server running the same version of CB that the plugin was made for?

 

Ohh Im sorry I left this post blank for a while,

All of my plugins are updated to the version I use 1.11. I downloaded a 1.12 jar for this plugin but then when I downloaded the previous version meant for 1.11, I had the same issue.
