AddOn is not working: Navigation Menus - quick & easy orientation

[Patrizia]

Hello, 

the AddOn: Navigation Menus - quick & easy orientation, ist not saving and showing my created menu. Is it a bug or am I doing something wrong?

I created the menu, I activated the menu and I click on save. But nothing happens. 

I'm still on the page. I can't see any created menu. And if I click on a different page, the menu that I created is gone. Even though I clicked on save. It's sad, because all the work is gone.

Ok, I found out, what the problem is: 

When I click on "get started" it looks, like you are able to create your menu. But nothing happens after clicking on save. 

But when I go to "configure" it shows the same mask, but when I save it there, it shows me that it is saved, after clicking on the button. And now I can see the menu.
