My two Blogs are linked together. How to Sepatare them?

Hi all, I started a new blog called https://theidealcopy.wordpress.com/
It seems to be another another site, crashpadthemovie.wordpress.com which is a site I set up for a filmmaker friend of mine. It seems my blog is “under” their blog and every time I write something, my post is under the author “Crashpad 520”. Also when I go to “my sites” the ideal copy is not there.

I can only access the ideal copy site, by tying in the web address to get there. In the meantime, I cannot do anything to change the settings. I want to start over again, but I want to keep the name “the ideal copy”. How do I reassign the name to another blog?
