Verification code is being send to a different phone number instead of my trusted phone number

In Appstore to update or download apps it wants my Apple Id password and then sends a verification code to my other trusted Iphone but I don’t have one. So when i select “didn’t get a verification code” it says to send a verification code to my trusted phone number but this number is wrong and I don’t know why. I went to settings and there the trusted phone number is right. I logged out of Appstore and then logged in but the trusted phone number stays the same and its wrong. I don’t have this number anywhere.
