Please add my code by now, so I will be able to check if it works also inside "Insights" if we talk about submenus.
Regarding the Main Menu items (About & Insights): it looks like you are using a "menu-separator" instead of a link.
Because of this, Joomla does not treat it as a "real" menu item, meaning it cannot hold an active status or be highlighted. This isn’t a bug with the Helix template or Joomla itself; it has actually functioned this way since Joomla 1.0 (2005).
In short: a Separator in a Joomla menu works just like a <hr> (horizontal rule) "divider" in HTML. It is meant for visual spacing, not for navigation. Yes, sometimes webmaster use it as typical Menu item, but ... it has its limitations/drawbacks.
