Hello,
Not sure if this is an error or not but I have noticed when selecting the Menu Item Type - "System Links" (which consist of: menu heading, menu item alias, separator, and url) you lose these tabs: Options, Page Display and Metadata and what you get is "COM_MENUS_PAGE-OPTIONS_FIELDSET_LABEL" (I have attached pictures)
I get when using the System Links menu item type you don't need the Options, Page Display or Metadata tabs (as these are already set in the main item) but it doesn't seem very intuitive as to what COM_MENUS_PAGE-OPTIONS_FIELDSET_LABEL means?
As always, hope this makes sense. I have noticed this happens in a variety of templates I am using and the quickstarts as well.
