Problem in wp-dtree categories

Hi!
My name is Nima Entesari
I’m the webmaster of http://www.allinfobazar.com web site.
Please look the link below:
http://allinfobazar.com/category/unique/
When you are surfing this page we have a problem with this step that the Other categories not work or disabled.
EX: ‘شرکتی’ is disabled and not work or we can’t click on it.
The other problem is that, when we have a sub-category, the category of the sub-category don’t have a link to click but it must have a link.

Please help me about this problem.
With Regards!
Nima Entesari.
