Okay, first of all, it's uploaded to the wrong sub domain. Instead of being uploaded to tv.adult-fanfiction.org, it's in original.adult-fanfiction.org.
You need to delete it from there, and reupload it to the proper subdomain.
To select the proper subdomain, while in your user/author panel, select "television" from the jump menu, press the go button, and then upload your story. The CSI category will then be available.
