Armor stand bugged

    So basically I'm working on a plugin rn that can summon an armor stand if stuff on it that follows you, but I'm running into a bug, whenever a player un-logs and re-logs, that player summons an armor stand that's invisible, HOWEVER, other players online CAN see it, so below there are screenshots of what it looks like. The first one if the one how un-logged, and you can see that both armor stands are invisible to the player unless you're in spectator, but on the second screenshot (taken by the person who watched the first player un-log and re-log ) the armor stand is there. I also checked whether or not mods affect it and it doesn't because my friend can see it (they don't use mods)

    Here's the code for the listener:
    Code:
    package de.ancash.pets.listeners;
    
    import org.bukkit.entity.ArmorStand;
    import org.bukkit.event.EventHandler;
    import org.bukkit.event.Listener;
    import org.bukkit.event.player.PlayerJoinEvent;
    import org.bukkit.event.player.PlayerQuitEvent;
    
    import de.ancash.pets.pets.PlayerPet;
    
    public class JoinListener implements Listener {
    
        @EventHandler
        public void onPlayerJoin(PlayerJoinEvent e) {
             new PlayerPet(0, 0, null, null, null, e.getPlayer());
        }
       
        @EventHandler
        public void onPlayerQuit(PlayerQuitEvent e) {
                PlayerPet.get(e.getPlayer().getUniqueId()).clear();
                PlayerPet.get(e.getPlayer().getUniqueId()).delete();
        }
       
    }
    
    and here's the "PlayerPet" it's referring to:
