SMS from unknown contact glitch after restoring messages

A

AC Question

Hi all,

I backed up all of my text messages with "SMS Backup & Restore". Since doing so, when an unknown sender sends me an SMS, it replaced the number part of the header with the title of the sender and replaces where the title should be with the contact name of someone I have stored. It also replaced the SMS profile photo with that of my friend's.

Thanks
