Approval Connection allow connection with the wrong password

Hi I'm using NetCode 1.7.0-pre-2 with Unet Transform but when I'm Starting to host I get the following warning: ![enter image description here][1]

and then when I'm starting to client and pass the wrong password it allow me to connect and it shouldn't

Heres my code:

 public class MainManu : MonoBehaviour
 {
     string Name;
     string Password;
     [Space] [Header("Name & Password")]
     [SerializeField] TMP_InputField Name_Text;
     [SerializeField] TMP_InputField Password_Text;

     // run when a client conncted to approval his connection
     void ApprovalCheck(byte[] connectionDate, ulong clientID, NetworkManager.ConnectionApprovedDelegate callback)
     {
         string Data = Encoding.ASCII.GetString(connectionDate);
         bool approveConnection = Data == Password;
         Debug.Log(approveConnection);
         callback(true , null, false, null, null);
     }
     public void Host()
     {
         byte[] Data = Encoding.ASCII.GetBytes(Password);
         NetworkManager.Singleton.NetworkConfig.ConnectionData = Data;
         NetworkManager.Singleton.ConnectionApprovalCallback += ApprovalCheck;
         NetworkManager.Singleton.StartHost();
     }
     public void Join()
     {   
         byte[] Data = Encoding.ASCII.GetBytes(Password);
         NetworkManager.Singleton.NetworkConfig.ConnectionData = Data;
         NetworkManager.Singleton.StartClient();
     }
 }

does any body have any idea how to enable ConnectionApproval?
