Android currently does not have a way to lock anything else other than the main lock screen. It sounds like you installed another ‘app locker’ type app. Do you remember what you may have installed? Check your all app list and see if anything stands out. If you can figure out which one is locking your settings, we may be able to figure out the steps to get though where you are getting stuck.
