why are my incoming text messages changing the saved phone number I have in my contacts?

[AC Question]

S4 ~~~~~ All of my incoming texts now have 1 1 (area code) + phone number. Even if the person is a saved contact in my phone, the incoming text changes the saved number to the new number with 1+1 in front of the phone number. I can't respond to that text. It states that the number is invalid.

That was a transient AT&T problem. They fixed it Wednesday morning, as I recall. (Maybe yesterday morning. I'm old, I forget things.)
