Yep, there is a bug and it's going to be fixed in the next update which I expect to get out tonight.
In the meantime if you see someone online through the server status page, you can send them a tell using their bioware name (the Player column) shown on there with /tp "Serissa1" for example.
Still a bug with the player list not refreshing names right after you dub them, will have a fix in soon. Should be fine when they login or you relogin any time after though.
