Can not fond room with the settings

Hello everyone. I have trouble with my photon connection to a room that has some settings. My room creation is here

RoomOptions ro  = new RoomOptions();
        ExitGames.Client.Photon.Hashtable ht = new ExitGames.Client.Photon.Hashtable();
        ht.Add("Type", 1);
        ro.CustomRoomProperties = ht;
        PhotonNetwork.CreateRoom(null, ro, null, null);

And connection to the room

       PhotonNetwork.JoinRandomRoom(new ExitGames.Client.Photon.Hashtable() {{ "Type", 1 }}, 4);

But when i want to connect second player to the room he creates new room instead of join. However, count of player in room that was created first is less then maximum number of players in this room. If i use this

      PhotonNetwork.JoinRandomRoom();

There are no problems. Thank you.
