Choral Public Domain Library

Hello,
please can you advise on how to edit the title of a piece of music.
Everything I've uploaded is correct but the title is appearing as Anthiphon instead of Antiphon in the list of choral works by Robert Page.
I just need to delete one letter in the title of the piece but I can't see how to do this.

Any help appreciated.

Thank you
Jonathan

Changing the title is allowed only to admins. I've done it accordingly.
