Submenu-Item is always visible

Hi,

I've assigned a menu to a superfish-block. The superfish block is in the same region as the menu. After I saved this, my menu is visible horizontal. So I think, that the superfish-menu has located my menu.

But my submenu-item is always visible. The alway-visible option, inside the link-settings is disabled. The cache is flushed and I have the libraries module installed. Why my submenu-link isn't visible? Hope anybody has a clue for a sulution.
