I was asked to make corrections/changes on the affidavits, which I did. Do I need to reprint the affidavits and have them signed and notarized again?

Yes. When the forms are signed and notarized, they are notarized based on the information on the forms at that time. Any changes to the forms must be observed and confirmed by the notary, who will then re-notarize the forms, affirming the changes are true and accurate.
