Need Help Related To OpenCart

Hi to all forum members I need some help I am using open cart for one of my project and their is almost 80 categories which I want to manage all the work is done but the bad part is that when I want to update Meta Title of any specific category the name of that category and all sub-category which comes in that category also changes with that title which I only want to use as a Title.SO help me in this please.

This is fully off topic.
