Creating categories is a little different from regular pages, and requires a more roundabout approach. What you do is go to the page you want to categorize, press the "Add category" button at the bottom, manually type out the name of the new category, and press enter. This creates a new category page.

I know this approach is basically the same as adding existing categories, but that's basically how the software does it. Let me know if you still need help.
