There is a difference between the display name (Wolf Link) and the handle (@justlookingfordragon ) the display name is initially, by default, the first part of the handle, as it is with your account. But you can change it. If you are linking the user, you have to use the handle, which is unique.
Voyager seems to ignore the display name and just displays the first part of the handle on its own. Which is indeed kind of confusing.
