Change my phone number in about device

[Alanhd]

I've just upgraded to nougat and I've noticed it's assigned another number as my phone number in about device. When I went into my my profile this other number number was in my profile along with the right number (no idea how it got there), I deleted it from my profile but it won't change in about device.
Is there a way to update my phone number. I've had this phone from new so no other number has ever been used with it.

Have you asked your carrier about this?

Agreed. Ask your carrier.
