SMS reply sending to wrong number

[thepoma]

This has happened twice so far, once when replying to a text from my dad and it's on going with texts from my mom.

I'll receive a text from my mom, the notification displays her number. When I do the quick reply within the notification and send it, it sends to her number but with a different area code that is one digit off from the right area code. When I open qksms and view my messages, her messages come in under the wrong area code number. Any idea why this is? I can post some screenshots if needed to better describe my issue.

Is this after backing up/restoring qksms' data with an external backup program? If so, rather than backing up the qksms' data, back up/restore the SMS database directly (apps like Migrate can do this). Duplicate of #1892.
