Mobile Site Submenu folder shows folder as an option

I have a folder in the navbar of my mobile site, the folder contains three pages. On desktop, the folder shows the three pages but when clicked but on mobile, the folder shows four items. The three pages AND the name of the folder also shows in the drop down menu.

Desktop view:



Mobile view:





What's the point of this? I don't think it should be there.
