Minecraft plugin that displays text above a player's head

I have the queue, display, and deletion working, the only issue is that there can be multiple ArmorStands/Messages at once, regardless of the fact that I have a Map associating a single armor stand with a player. When the display function is called, it checks if there is an associated armor stand, and deletes it (before i get queue working, i want there to be one message displayed at a time) 
public final Map<Player, ArmorStand> playerArmorStand = new HashMap<>();

public void messageDisplay(Player p, String m){
        if (playerArmorStand.containsKey(p)) {
            ArmorStand existingStand = playerArmorStand.get(p);
            existingStand.remove();
            playerArmorStand.remove(p);
        }

        // Set variables to be used
        Location loc = p.getLocation();
        World world = p.getWorld();
        ArmorStand chat = world.spawn(loc, ArmorStand.class);

        // Associate a specific armor stand with the player
        playerArmorStand.put(p, chat);
...
public final Map<Player, ArmorStand> playerArmorStand = new HashMap<>();

        if (playerArmorStand.containsKey(p)) {
            ArmorStand existingStand = playerArmorStand.get(p);
            existingStand.remove();
            playerArmorStand.remove(p);
        }

        // Set variables to be used
        Location loc = p.getLocation();
        World world = p.getWorld();
        ArmorStand chat = world.spawn(loc, ArmorStand.class);

i got it so that only one message displays at a time, but the reason for it not working in the first place is the fact that maps are not being saved outside of the functions i have decided i will have all the map logic inside of functions and passed through each other would not work i think actually
