Sidebar Categories Questio

I added five categories through widgets on my primary sidebar. Under each of them, all of my main categories that have posts in them are coming up. However, I only want certain categories to come up in each of them, not all the categories that have posts. I attached an image of the issue. So under CSU Northridge, I only want the CSU Northridge General to come up while under SDSU, I only want the SDSU Ceneral to come up. Does anyone know how to fix this? Thank you.
