GUILayout.TextField Refresh

Hi! I have a GUILayout.Textfield which I use to enter a new player name. However, the text in the textfield never gets refreshed although the value does change according to the console logs. Any idea how to get the text field to refresh?

Edit for code: private bool createProfile = false; private string playerName = "PlayerName";

 void OnGUI()
 {
   //Display window to enter player name.
   if (createProfile)
   {            
     Rect createProfileWindow = new Rect(Screen.width / 2 - 100, Screen.height / 2 - 35, 200, 70);
     createProfileWindow = GUILayout.Window(2, createProfileWindow, CreateUserProfile, "New player");
   }
 }
 
 void CreateUserProfile(int windowID)
 {
   //Pop up window to introduce player name. Add 'create' button.
   GUILayout.BeginVertical();
   GUILayout.BeginHorizontal();
   GUILayout.FlexibleSpace();        
   playerName = GUILayout.TextField(playerName, 50);    
   GUILayout.FlexibleSpace();
   GUILayout.EndHorizontal();
   GUILayout.BeginHorizontal();
   GUILayout.FlexibleSpace();
   if (GUILayout.Button("Create"))
   {
     PlayerPrefs.SetString("PlayerName", playerName);
     PlayerPrefs.Save();
     createProfile = false;
   }
   GUILayout.FlexibleSpace();
   GUILayout.EndHorizontal();
   GUILayout.EndVertical();
 }
