ItemStack changing its amount.

So I'm trying to write a fix for dropping items {

when you drop an item, if the event is cancelled, it will set it to the first empty in your hotbar; I am trying to keep it in the current slot.

I have managed to do so sufficiently, but when I retrieve the item, the ItemStack size is always 1;

What could I do to fix this?

Here's my code:

Code:java

    @EventHandler(priority = EventPriority.HIGH)
    public void onDrop(PlayerDropItemEvent event) {
 
        if (plugin.getConfig().getBoolean("Fixes.Drop")) {
 
            Player player = event.getPlayer();
 
            final Item item = event.getItemDrop();
            ItemStack itemStack = item.getItemStack();
 
            if (event.isCancelled()) {
 
                event.setCancelled(false);
 
                item.remove();
 
                ItemStack droppedItem = itemStack.clone();
 
                player.setItemInHand(droppedItem);
 
            }
 
        }
 
    }

Thanks.
