Bug Extra Hearts

For some reason, when I put this enchant on, it does not give me extra hearts in 1.9. However, when I went back to an older version of spigot, it gave me them....

Code (Text):

public class Health extends CustomEnchantment {

    static final Material[] SPEED_ITEMS = new Material[] {
            Material.LEATHER_CHESTPLATE,
            Material.IRON_CHESTPLATE,
            Material.CHAINMAIL_CHESTPLATE,
            Material.GOLD_CHESTPLATE,
            Material.DIAMOND_CHESTPLATE
    };

    public Health() {
        super("Health", SPEED_ITEMS, 2);
        this.max = 2;
        this.isTableEnabled = false;
    }

    @Override
    public void applyEquipEffect(Player player, int enchantLevel) {
        player.setMaxHealth(26);

    }

    @Override
    public void applyUnequipEffect(Player player, int enchantLevel) {
        player.setMaxHealth(20);
    }
}
