SM-G925V on AT&T Call come in displayed in International Format

Hi again everyone
I have Verizon S6 edge on 5.1.1 and I am using my AT&T sim card. The phone calls come in displayed +34 532 5678 etc. 😮

The phone is not in Global Mode it is on LTE?GSM/UTMS but it doesn’t matter all the calls come in this format.
also this is a common occurrenceon various samung model such as Gsm unlocked SM-G900P ,SM-G910P, and so on.

Is there a fix I have tried manipulating call settings by turning off and on international assist neither work

Thanks in Advance to help
