Hello there, @MB9251
I certainly want to assist you further with this matter. To better do that, can the Community have some added details about your specific device and this concern? Things that will help the most would be the exact model number and Baseband version (both under Settings>About Device) for your device as well as your carrier. Thanks!
Short of having to manually set it back, have you tried any other troubleshooting steps to try and correct/prevent this?
Let's try some other troubleshooting steps, just let me know how these go!
