In this version I've added fixed:

• security.custom-named function now works as it should (Bug discovered by: @Antrox).
• Added PT-BR language support (Submitted by @RafricOFC).
• Added a setting to disable the recycle again button (Requested by @RafricOFC).
• Compiled the plugin with the latest Spigot version.
• General optimization.

If you want to disable the Recycle again (orange button) set:
gui:
disable-recycle-again: true
