Suffix After Entering in Command

Hello everyone, my problem is I have this suffix after I enter in my commands. They work perfect, but they have that same suffix every time!

Here is a screenshot of the problem:

This is my onCommand section. My plugin.yml is set up.

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
Player player = (Player) sender;
if(commandLabel.equalsIgnoreCase("record")){
Bukkit.broadcastMessage((player.getDisplayName () + ChatColor.AQUA + " is recording a video!"));
}
if(commandLabel.equalsIgnoreCase("stream")){
Bukkit.broadcastMessage((player.getDisplayName() + ChatColor.AQUA + " is livestreaming!"));
}
if(commandLabel.equalsIgnoreCase("charity")){
Bukkit.broadcastMessage((player.getDisplayName() + ChatColor.AQUA + " is livestreaming for charity"));
}
if(commandLabel.equalsIgnoreCase("end")){
Bukkit.broadcastMessage((player.getDisplayName() + ChatColor.AQUA + " has ended their recording/livestream!"));
}
if(commandLabel.equalsIgnoreCase("youtubeannouncer")){
sender.sendMessage(ChatColor.GOLD + "----------------------------------------");
sender.sendMessage(ChatColor.BLUE + "YoutubeAnnouncer");
sender.sendMessage(ChatColor.BLUE + "Developed by MineStein");
sender.sendMessage(ChatColor.RED + "Command Citation:");
sender.sendMessage(ChatColor.GREEN + "/record | Alerts users of your recording | p: youtubeannouncer.record");
sender.sendMessage(ChatColor.GREEN + "/stream | Alerts users of your livestream | p: youtubeannouncer.stream");
sender.sendMessage(ChatColor.GREEN + "/charity | Alerts users of your charity livestream | p: youtubeannouncer.charity");
sender.sendMessage(ChatColor.GREEN + "/end | Alerts users to the and of your stream/recording/event | p: youtubeannouncer.end");

sender.sendMessage(ChatColor.GOLD + "----------------------------------------");

 

You have to make your onCommand return true, not false
