I was setting up Support System in Pro-Sites and only had 3

I was setting up Support System in Pro-Sites and only had 3 questions in the FAQ when I decided to structure it differently. I deleted the questions and now its showing 1 question in the general tab and 65533 questions in the Themes category tab I created. How do I clear these tabs? I went into my database but did not want to delete anything until I received a little feedback.

Thanks
