Try Reset All Settings. This will reset the fingerprint set up. Among other things, you will have to add your prints back in.
Reset All Settings
Go to Settings >General >Reset >Reset All Settings. This resets to default everything in Settings, including notifications, alerts, brightness, and clock settings like wake up alarms.
Let us know if it works or not.
