[PUN] Duplicates data in master client and client custom properties

I guys. I face a strange behaviour with PUN. This is my use case : I have two players, ted and kosted.

Let's suppose that kosted creates the room. In the room he sets his custom property and get "type = Rouge". When the 2nd player joins this room get get the "type=Bleu".

 if (PhotonNetwork.isMasterClient) //master client is the first to connect
         {
             Debug.Log("je suis dans le master");
             ExitGames.Client.Photon.Hashtable infoJoueur = new ExitGames.Client.Photon.Hashtable();
             //On instancie les infos sur son profil
             infoJoueur.Add("type", "Rouge");
             infoJoueur.Add("typePlayer", "player");
             infoJoueur.Add("wantReplay", "Null");
             PhotonNetwork.player.name = j.pseudo;          
             infoJoueur.Add("pseudo", j.pseudo);
             PhotonNetwork.player.SetCustomProperties(infoJoueur);
 
             GameObject profilR = PhotonNetwork.Instantiate(prefabProfilRouge.name, pivotRouge.transform.localPosition, Quaternion.identity, 0);
             int view = profilR.GetComponent<PhotonView>().viewID;
             
             GestionInteraction gi = profilR.GetComponent<GestionInteraction>();
             gi.majInfoProfil(view,j.pseudo, victoireDefaite, panelAttenteMatchingJoueur);
 
 
         } else { //we have the 2nd player
 
             ExitGames.Client.Photon.Hashtable infoJoueur = new ExitGames.Client.Photon.Hashtable();
             infoJoueur.Add("type", "Bleu");
             infoJoueur.Add("typePlayer", "player2");
             infoJoueur.Add("wantReplay", "Null");
             PhotonNetwork.player.name = j.pseudo;            
             infoJoueur.Add("pseudo", j.pseudo);
             PhotonNetwork.player.SetCustomProperties(infoJoueur);
            
 
             PhotonPlayer[] listeJoueur = PhotonNetwork.playerList;
             ExitGames.Client.Photon.Hashtable infoPlayerRouge = listeJoueur[0].customProperties;
             ExitGames.Client.Photon.Hashtable infoPlayerRouge2 = listeJoueur[1].customProperties;
 
             Debug.Log(infoPlayerRouge["type"].ToString() + " " + infoPlayerRouge2["type"].ToString());
             Debug.Log(infoPlayerRouge["typeJoueur"].ToString() + " " + infoPlayerRouge2["typeJoueur"].ToString());
 
             PhotonNetwork.room.open = false; //On ne peut plus accéder à la room
             PhotonNetwork.room.visible = false; //La room n'est plus listée parmi la liste des room du lobby
      
         }
     }

When I get type in the type of the master client I got Rouge, and the type of client is Bleu.

The issue come when i make my two players leaves the room. The ancient client creates a new room and become the master client, and the previous master client joins the room as a client. But when i try to get the custom property type, sometimes i get "Bleu" or "Rouge" for both.

But normally it's not possible, because accoding to my previous code, master client and client doesn't execute the same code. This custom property is never modified in my app, so i don't know how they do to have the same custom property.

Please how could I do ?
