Text on UI Button Not Updating

Hi there,

I have a button that's suppose to toggle between a map editor and the game state. The button correctly toggles the game state, but it does not correctly update the text on the button. Yet if I debug the button text...it shows that it should have changed. I have absolutely no idea what to do here. Code:

     [SerializeField] Button mapEditorButton = default;
     string mapEditorButtonLabel;
     
     private void Start()
     {
         mapEditorButtonLabel = mapEditorButton.GetComponentInChildren<Text>().text;
    }    
 
    public void ToggleMapEditor() {
         bool mapEditorActive = Game.Instance.GetInputState().GetType() == typeof(InputEditorDefault);
 
         if (mapEditorActive) {
             mapEditorButtonLabel = "Open Map Editor";
             Game.Instance.PopInputState();
         }
         else {
             mapEditorButtonLabel = "Return to Game";
             Game.Instance.LaunchMapEditor();
         }
 
         Debug.Log(mapEditorButtonLabel);
         Debug.Log(Game.Instance.GetInputState().GetType());
     }

The button eternally shows the placeholder text I have for it, despite the following output:
