Solved Getting messages twice when right clicking endercrystal?

So i got this code:

Code (Text):

    @EventHandler
    public void onInteract(PlayerInteractEntityEvent e) {
       
        if(e.getRightClicked().getType() == EntityType.ENDER_CRYSTAL) {
            if(points.getInt("points." + e.getPlayer().getUniqueId()) == 0) {
                e.getPlayer().sendMessage(Crates + "§5You got no points!");
            }else if(points.getInt("points." + e.getPlayer().getUniqueId()) > 0) {
                playCrateEffects(e.getPlayer());
                    int kills = points.getInt("points." + e.getPlayer().getUniqueId());
                    points.set("points." + e.getPlayer().getUniqueId(), Integer.valueOf(kills - 1));
                    e.getPlayer().sendMessage("§7T");
                  try {
                    points.save(file);
                  } catch (IOException e1) {
                    e1.printStackTrace();
                  }
            }
        }
            }

And everytime i click the ender crystal, it sends the "T" message twice. I know it's the 1.9 update, two hands. But i found nothing that really helped.

Thanks.

 

I know why it's comming. And how could a runnable fix that?

 

Thank you! It worked, thanks to @BananaPuncher714!
