i have a lot of sub categories under each main category. so when i click on the main category, it has this huge title text show up on top of the post, listing all the sub categories i have under this category. how do i limit it to show only the main category and not everything under it?

i look at the skin files, but i haven't been able to find the lines that can change it. i assume it's among the b2evocore files? which one? any pointers?

thanks a lot!
