Category Page Issue

Hello, I’m using the Pro version of Q&A. All is going well until the category part. Whenever I click on any of the categories in the sidebar, it calls up a wrong page, since it would appear to show the sorted questions regarding that category but shows on a wrong page–the sorted question would be listed on a page with wrong page title (i.e. one of the posted questions as a title).

1. How to fix?
2. What page should these sorted questions category appear on?

Thanks in advance!
