Notes locked & will not let me use fingerprint

Please help! I’ve locked the note within the Notes app that has ALL of my passwords on it (including my Apple password) with my fingerprint. I have an 7+. I thought this was a safe way to keep my passwords. For reasons I do not understand, that Note now demands my apple password which I no longer remember and thought safe to be used inside with my fingerprint. I cannot get back to a fingerprint option. All other apps that require my fingerprint work, but not my one note that I thought was always accessible because of the finger option. How do I get back to that option?
