Yes. This happened because you joined via Facebook. You cannot simply switch the positions of the names; there is officially only one username. If you want Dredknight to be your username, you will have to rename your account. You can do so at Special:UserRenameTool. However, you should be sure you want to do this. Each account may be renamed once and only once. Additionally, renames cannot be reverted nor can a new account be opened under the previous username.
