If open the menu show me all players duplicate like this:

1 Martin
2 Martin[Offline]
3 Bob
4 Bob[Offline]
5 Jack
6 Jack[Offline]

How can stop that?

	new menu = menu_create( "\y[\rArena\y]", "choose_playermenu_handler");
	menu_additem(menu, "\r[!]\yUpdate players\r[!]^n\yChallenge a player:", "0", 0);
	new players[32], pnum;
	new szName[32], szTempid[32], Desc[64];
	get_players(players, pnum);
	for (new i; i<pnum; i++)
	{
		Challenged = players[i];
		if (is_user_alive(Challenged) && (Challenger != Challenged))
		{
			get_user_name(Challenged, szName, charsmax(szName));
			formatex(Desc, charsmax(Desc), in_Duel[Challenged] ? "\d%s \y[\rIn Arena\y]" : "%s", szName);
			num_to_str(Challenged, szTempid, charsmax(szTempid));
			menu_additem(menu, Desc, szTempid, 0, g_MenuCallback);
		}
                if(his_offline[Challenged])
                {
                        formatex(Desc,charsmax(Desc), "\y%s \w[\rOffline\w]", szName);
			menu_additem(menu, Desc, szName, 0, g_MenuCallback);
                }
	}
