Submenus alway opend (expanded)

Hello

Somehow all of my menu items are alway opened. The second level items are always visible. I want them to show up when you click the first level item (like in the demo).

What I already tried:
– Deactivate all other plugins

Widget Settings:
[x] Auto Close Open Menus
[x] Save Menu State (uses cookies)
[x] Auto Expand Based on Current Page/Item

Did someone have the same issue, or has an idea what I’m doing wrong?

Thanks!

Mike
