Can't edit navmenu on subdirectories after cloning with Cloner

I've installed multisite and the plugin Cloner. I've cloned 5 sites so far. When I'm navigating to my subsites/subdirectories menu options, I'm not able to do any change. It looks like it's just not responding on anything. The only option I have is to create a new menu. But when I'm trying to create a new menu, it won't do it.

Do you have any idea what might be wrong?
