On my freelance payroll, under "editor signature", do I leave it blank?

OK, I'm stupid and new to this, so I don't know if I should sign it because I'm not the editor, just a writer. Yet, I can't help wondering if the signature line is for me because I'm meant to complete the form and send it in....usually one has to sign these things, but the "editor" bit throws me off. Should I leave it blank?
