I have this same issue. During the free trial period I had made an 2nd character of a different race just to get the feel for it and decide which one I wanted to play as my primary character. Now that my free trial is over and I just pay the basic one character per world sub, I still have two characters listed under my home server, but the one I don't use is blacked out and has a red X next to its name. You can't delete it because you can't select it. Usually you can just right click the character name and delete, but that's not possible. Just minor annoyance, but it is a flaw in the user interface for anyone who doesn't pay for multiple characters.
