No dropdown menu on pages?

Ok so i’ve probably just overlooked some settings somewhere but i cant get my drop down menu on my page to work, it only shows up on the homepage. not on any of the parent or child pages.

I’m using latest platform theme(free version) and it’s supposed to be able to show both a drop down menu and all the child pages (right under the topnavigation bar) when u enter a parent or childpage. What should i do?

my adress is https://www.storstadykoping.se (it’s in swedish)

Thanks in advance!
Best regards, Patrik
