+1 Issue with Your Phone

How can I eliminate the above noted issue when using "Your Phone" on my windows 10 version 1909. I have asked for and received assistance, remotely, from two (2) Microsoft techs with no results. Am I the only one experiencing this issue? If so, how can I resolve it. My phone is a Note 8. My cotacts do not ontain the "+1" designation. It only appears on the PC, Acer 5, when I attempt to make a call. HELP!!!
