php - Laravel Nova 4.0 the old value does not remain on update action

one text

When I want to update, an item does not remain old selected option (value). What can I do to keep option on current value ? This is field() lines:

  public function fields(NovaRequest $request)
    {
        return [
            ID::make('id')->sortable(),
            Text::make('Title'),
            Select::make('Type')->options(FormElementType::cases())->default('field')->resolveUsing(function () {
                return $this->type ?? 'map';
            }),
           

        ];

    }
