Solved ArmorStand properties not updating

I'm trying to create a hologram using NMS but whenever I spawn in the ArmorStand using PacketPlayOutSpawnEntityLiving, it spawns the default armor stand and changes nothing else, even if I try changing its properties. Of course, I could just be really stupid and making a careless mistake but if you have an idea or you know, help is appreciated!

VERSION = 1.16.3

What I have checked so far:
- If the properties are actually changing, which they are. They are just not showing in-game.
- If the armor stand was added, which it is.
- If the text is null, which it isn't.

Code:

 lines.forEach(text -> {
            EntityArmorStand armorStand = new EntityArmorStand(EntityTypes.ARMOR_STAND, worldServer);

            System.out.println("TEXT = " + text);

            armorStand.setCustomName(new ChatComponentText(ChatUtils.format(text)));
            armorStand.setCustomNameVisible(true);
            armorStand.setInvisible(true);
            armorStand.setSmall(true);
            armorStand.setNoGravity(true);
            armorStand.setBasePlate(false);
            armorStand.setMarker(true);
            armorStand.setPosition(location.getX(), location.getY(), location.getZ());

            System.out.println("CUSTOM NAME VIS = " + armorStand.getCustomNameVisible());
            System.out.println("INVSIIBLE = " + armorStand.isInvisible());
            System.out.println("SMALL = " + armorStand.isSmall());
            System.out.println("NOGRAV = " + armorStand.isNoGravity());
            System.out.println("BASEPLATE = " + armorStand.hasBasePlate());
            System.out.println("IS MARKER = " + armorStand.isMarker());

            armorStands.add(armorStand);
            System.out.println("ARMOR STAND ADDED!");
        });

Nvm I fixed it. I just had to send PacketPlayOutEntityMetadata as well. Why are there extra steps to spawning in mobs now
