Trackbacks Showing up as "Anonymous"

My trackback posts are showing up as “anonymous.”

For example, I linked to a piece in one of my posts. That link is showing up as a trackback in the comments section of the aforementioned piece. However, the trackback is showing my post as “anonymous.”

This makes no sense. My blog has a name and a unique URL. So there is nothing “anonymous” about it.

The problem, of course, is that by showing up as “anonymous,” my blog isn’t able to build up a following and name recognition.

Please advise as to how I can fix this problem. Thanks!
