Accidentally Deleted Category

Accidentally Deleted Category

While playing around with Support on my first day using it, I created a Category for the Help Center using the name of one of our programs; then I thought it wasn't what I wanted to do and deleted it. Now I realize it WAS what I wanted to do, but now when I try to create a Category with that name, I get the error "Already a category/ section exists in this name. Please change it." How can I fix this so that I can create this Category?
