Category/Sub Category Post Issue

Hi WordPress,

I installed wordpress in my directory:- http://www.cbdmovers.com.au/suburbs/

I have a category page about Melbourne:- http://www.cbdmovers.com.au/suburbs/?p=66

This one is sub category page whose parent category is Melbourne:-
http://www.cbdmovers.com.au/suburbs/?cat=34

When I create any sub category page and make a post, I found that the article which I posted in main category (I mean at http://www.cbdmovers.com.au/suburbs/?p=66 ) is showing at the bottom of post. You may check out http://www.cbdmovers.com.au/suburbs/?cat=34 and you will find these lines:-

I haven’t posted this line in my article but wordpress fetched it from parent category page (i mean from http://www.cbdmovers.com.au/suburbs/?p=66 ).

Please have a look and suggest me possible solution.

Thanks and Regards,
