Superfish wordpress

Superfish wordpress

Hi experts,

I'm using superfish for my wordpress, but got a problem that I need your help to fix.

http://fabuloussystem.com/category/product/radio

In " Radio " category, it suppose to show only " Lincoln " but not all the post under Radio. The same thing at " Lincoln " category, it suppose to show only " walkie-talkie " but not FM701 which is under " walkie-talkie " category.

The category flow as below:

Product > Radio > Lincoln > Walkie-talkie > FM701

Anyone can help me on this? Appreciate it much!
