Subnavigation on Category

How to I add/remove a subnavigation item from a Category on the Home page. So based of the image (see link) I want to remove Popular and just have New and Subcategories. I have gone over the whole theme and I just can’t seem to find away to achieve this. Any help is much appreciated. Thanks in advance.
