Strange behavior with if statement inside foreach

I want to have a score board (for now it's only showing pings but whatever) that player can look when they want. Here's my initial code :

 IEnumerator MAJTableauScore () 
     {
         while(Input.GetButton("Score"))
         {
             playerlist.text = "";
             foreach(PhotonPlayer playR in PhotonNetwork.playerList){
                 playerlist.text += playR.name + "  : " + playR.customProperties["Ping"]  + joueur.customProperties["Team"] + "\n";
             }
             yield return new WaitForSeconds(4f);
         }
     }

It's working fine, it shows the correct team for each player.

Now I want to add have my list like this :

 Team 1:
 *list of the players in team 1*
 
 Team 2
 *list of the players in team 2*

So I do this :

 while(Input.GetButton("Score"))
         {
             photonView.RPC ("updatePing", PhotonTargets.AllViaServer);
             playerlist.text = "";
             playerlist.text += "Team 1" + "\n";
             foreach(PhotonPlayer playRin PhotonNetwork.playerList){
                 if (playR.customProperties["Team"] == "team1") playerlist.text += playR.name + "    : " + playR.customProperties["Ping"] + "\n";
             }
             playerlist.text += "\n" + "Team 2" + "\n";
             foreach(PhotonPlayer playRin PhotonNetwork.playerList){
                 if (playR.customProperties["Team"] == "team2") playerlist.text += playR.name + "    : " + playR.customProperties["Ping"] + "\n";}
             yield return new WaitForSeconds(4f);
         }

Now it doesn't work anymore, it only shows the player running the code.
