C# Unity新输入系统未显示序列化字段

我正在使用Unity 2019.1.4f1，刚刚从软件包管理器获得了新的Unity输入系统。我无法在打算使用它的MonoBehavior中看到用于链接生成的C#类的序列化字段

我已经公开并向实例添加了[SerializeField]属性，但它不会在检查器中显示该字段。 因此，我尝试在Monobehavior中以编程方式创建实例，但它不起作用。未调用我的SelectDestination方法

public class PlayerInputManager : MonoBehaviour
{
    [SerializeField]
    public PlayerInput Input;

    private void Awake()
    {
        Input = new PlayerInput();
        Input.Enable();        
    }

    void OnEnable()
    {
        Input.Player.SelectDestination.performed += ctx => SelectDestination();
        Input.Player.SelectTarget.performed += ctx => SelectDestination();
        Input.Player.W.performed += ctx => SelectDestination();
        Input.Player.Enable();
    }

    void OnDisable()
    {
        Input.Player.SelectDestination.performed -= ctx => SelectDestination();
        Input.Player.SelectTarget.performed -= ctx => SelectDestination();
        Input.Player.W.performed -= ctx => SelectDestination();
        Input.Player.Disable();
    }

    void SelectDestination()
    {
        Debug.Log("BLA");
    }
}

当按下W、左键单击或右键单击时，应记录“BLA”

如果使用此选项，Unity将根据我的播放器输入导入设置生成以下代码：
