CMS How do you remove categories when there are no sections listing them?

[محروم.كوم]

I loaded the demo CMS content and removed a lot of sections and articles. Now I can't seem to find out how to remove the categories. They are listed on the left side of the home page with numbers in the "(x)" but then it says "I find no available content in category......" when you select it.


I want to remove the categories that I don't need. __DEFINE_LIKE_SHARE__
