Homestead forces you to add a company name - how do you change it later?

Clicking on the company name does not allow me to change it. I put something in as a placeholder and now I can't change it. Would appreciate any help you can provide. A) Homestead shouldn't force us to add a company name, B) Homestead shouldn't force us to add an email address. C) If Homestead forces us to add anything, it should be easy to change it.
