The reason it's listed as a masculine name is because the only evidence of use Sofia could find was a male bearer in Suriname. Do you have any proof that it's a feminine name or of feminine usage?
(P.S.: If you're the one who repeatedly submits duplicates of that same name, I'd like to ask you to please stop. We editors have to keep deleting them, and it's rather tiresome.)
