"BUG" Player visibility

Help! how to see the players and mobs

Code:

public class Dimension {
    public static void setDimension(Plugin plugin, String world, int dimension, WorldType type) {
        WrapperPlayServerRespawn wp = new WrapperPlayServerRespawn();
        wp.setLevelType(type);
        wp.setDimension(dimension);
        wp.setGameMode(NativeGameMode.ADVENTURE);
        wp.setDifficulty(Difficulty.HARD);

        for (Player p : Bukkit.getOnlinePlayers()) {

            Location location = p.getLocation();
            int viewDistance = plugin.getServer().getViewDistance();

            int xMin = location.getChunk().getX() - viewDistance;
            int xMax = location.getChunk().getX() + viewDistance;
            int zMin = location.getChunk().getZ() - viewDistance;
            int zMax = location.getChunk().getZ() + viewDistance;
            wp.setGameMode(getGamemode(p.getGameMode()));
            wp.sendPacket(p);
            for (int x = xMin; x < xMax; ++x) {
                for (int z = zMin; z < zMax; ++z) {
                    Bukkit.getWorld(world).refreshChunk(x, z);

                }
            }
            p.updateInventory();

        }
    }

    public static void setDimensionOnPlayer(Plugin plugin2, String world2, int dimension2, WorldType type2, Player player2) {

        WrapperPlayServerRespawn wp1 = new WrapperPlayServerRespawn();
        wp1.setLevelType(type2);
        wp1.setDimension(dimension2);
        wp1.setGameMode(NativeGameMode.ADVENTURE);
        wp1.setDifficulty(Difficulty.HARD);

        wp1.setGameMode(getGamemode(player2.getGameMode()));
        Location location = player2.getLocation();
        int viewDistance = plugin2.getServer().getViewDistance();

        int xMin = location.getChunk().getX() - viewDistance;
        int xMax = location.getChunk().getX() + viewDistance;
        int zMin = location.getChunk().getZ() - viewDistance;
        int zMax = location.getChunk().getZ() + viewDistance;

        wp1.sendPacket(player2);
        for (int x = xMin; x < xMax; ++x) {
            for (int z = zMin; z < zMax; ++z) {
                Bukkit.getWorld(world2).refreshChunk(x, z);

            }
        }
        player2.updateInventory();

    }

    public static NativeGameMode getGamemode(GameMode gm) {

        NativeGameMode gamemode = NativeGameMode.SURVIVAL;
        if (gm.equals(GameMode.ADVENTURE)) {
            gamemode = NativeGameMode.ADVENTURE;
        }
        if (gm.equals(GameMode.CREATIVE)) {
            gamemode = NativeGameMode.CREATIVE;
        }
        if (gm.equals(GameMode.SURVIVAL)) {
            gamemode = NativeGameMode.SURVIVAL;
        }

        return gamemode;
    }
}
