p.sendMessage("msg") firing twice

I need help. My plugin keeps firing the p.sendmessage twice in game. It cancels the event but the no permission message is firing twice, I really need some help. (Worldgaurd kinda thing)

Code:

@EventHandler
public void onBreakBlock(BlockBreakEvent e) {

Player p = e.getPlayer();

if (p.hasPermission("worldgaurd.break.permission")) {



}else {

e.setCancelled(true);

p.sendMessage(ChatColor.BOLD + "" + ChatColor.AQUA + "Server" + ChatColor.GRAY + ">> " + ChatColor.RESET + ChatColor.RED + "You don't have permission");

}

}

 

Main

Code:

@SuppressWarnings("unused")
public class CoreHub extends JavaPlugin {

public void onEnable() {
System.out.println("Plugin enabled (!)"); <- I know I don't need it but makes me feel better :D

[here is a list of 10000000 events being registered. So I only put the class I was talking about]

Bukkit.getServer().getPluginManager().registerEvents(new WorldProtection(),this);

Code:

public class WorldProtection implements Listener {

@EventHandler
public void onBreakBlock(BlockBreakEvent e) {

Player p = e.getPlayer();
if (p.hasPermission("worldguard.break")) {



}else {

e.setCancelled(true);
p.sendMessage(ChatColor.BOLD + "" + ChatColor.AQUA + "Server" + ChatColor.GRAY + ">> " + ChatColor.RESET + ChatColor.RED + "You don't have permission");}

}

Pretty sure the reason is that world guard is displaying a message, and your plugin is displaying a message. I didn't get to see the actual screenshot of the messages so I may not be correct
EDIT: Do you have the WorldGuard plugin or not?
