Clicking Menu Title is Redirecting URL

If you click on any of the menu items that have a list (Connect, Open, Export, Charts), and instead of clicking on an actual item in the list, you click on the title, you'll see the URL has changed.

For example, if you go to your Demos page, and click on "Charts", the list appears of different charts, BUT instead click on the title "Charts", and you'll notice that the url changes from "https://www.flexmonster.com/demos/js/pivot-table/" to "https://www.flexmonster.com/demos/js/pivot-table/#" (extra # at the end).

In our SPA application, when you click on the title, it actually redirects to our home page.
