Comment Link is Sending to Hidden Blog

I had an old blog which I made hidden when creating my new blog. The new blog is set as primary and is the only one NOT hidden. I recently left a comment on another blog and the blogger clicked on my name and it took them to my old, hidden blog and NOT my new one.

If I have a blog that is hidden, shouldn’t it be actually HIDDEN?

Also, I cannot seem to locate how to set it so that my external comments link to my current blog. Help!
