Don’t sweat this. The financial aid process is confusing to many people - not just you. The school Financial Aid office personnel really are there to help you navigate the process. Since they have limited funds to disperse, they naturally have rules they have to follow, but they aren’t going out of their way to single you out and dash your college dreams.
They will explain what they need from you, and why - or how they use the information they are asking for. They are just doing their job to be fair to everyone, and they would treat everyone in your situation the same way.
