GH_TaskCapableComponent missing parallel option when appendmenu

I don’t know if anyone has encountered this yet, but when I created a task capable component with some custom menu options, I am now unable to access the option to toggle between parallel and ordered.

public class SpanCheckPurlin :     
GH_TaskCapableComponent<SpanCheckPurlin.SolveResults>
    {
        public SpanCheckPurlin()
          : base("SpanCheck", "CheckSpan",
              "Check whether the purlin or girt can support such a wide span.",
              "NCEng", "Purlins & Girts")
        {
            Message = "Purlin";
        }

        public override void AppendAdditionalMenuItems(ToolStripDropDown menu)
        {
            Menu_AppendSeparator(menu);
            Menu_AppendItem(menu, "Purlin", PClick, true, Element == 0);
            Menu_AppendItem(menu, "Fascia", PClick, true, Element == 1);
            Menu_AppendItem(menu, "Girt", PClick, true, Element == 2);
        }

Try:

    public override void AppendAdditionalMenuItems(ToolStripDropDown menu)
    {
         base.AppendAdditionalMenuItems(menu);

to run the code of the GH_TaskCapableComponent method.

forgot about the base.
