Hello all, thanks for your patience with a newb.
I'm getting more and more comfortable with using Calibre,but I'm stumped with this.

In the "edit metadata individually" window, how do I delete incorrect entries in the Author field? I have some typos, misspellings, and just wrong information that I would like to clear out. I see that I can delete series entries one at a time. Is there something similar for the author field?

Thank you
