problem when try add customer number

Hello greetings! I just realized that when trying to add a client from the dashboard, I select the flag of my country and put the number, but then when saving, it is without the country code, for example it should be +1 123456, but when saving simply It does not save the country code and only 123456 remains, so it affects me when trying to send notifications by sms because it gives me an invalid number
