Unity event listeners receiving the event notification at different times

I am trying to have multiple objects respond to a game pause state, this works fine when first running the scene however after restarting the scene the listeners are responding at different times.

The event that sends the message is:

globalGameState = newState;
GameStateChanged?.Invoke(globalGameState);

And the listener:

    private void OnEnable()
    {
        Globals.GameStateChanged += GetStateChange;
        _correctState = false;
    }

    private void OnDisable()
    {
        Globals.GameStateChanged -= GetStateChange;
    }

    void GetStateChange(GlobalGameState state)
    {
        if (state == _compareState) { _correctState = true; return; }
        _correctState = false;
    }

I have checked and made sure that all the objects are subscribing / unsubscribing to the event correctly, I just cant find what would cause it to stop working only when the scene has been restarted. (The scene restart is a simple SceneManager.LoadScene();)

In the second image there are 8 that run on a different timer, every pause or restart after that it is always the same 8 that are de-synced. Restarting unity changes the number in the de-sync batch.

Any idea as to why some are receiving the event on a different timer is welcome.
