When changing or updating the customer name, the sold to field doesn't get updated automatically

While creating Receivables Transaction(Invoice) the sold to field in Customer section get updated automatically once bill to customer entered. If we change/update the bill to customer it's not get updated the sold to field as per the change.

Another Scenario: If we are duplicating the existed invoice and update the customer information in Bill to field it's not get updating in Sold to field. Since it's not giving an error to complete the invoice we are capturing incorrect customer information.

Could you please suggest how can we update this "Sold to" field as per the customer selection in Bill to every time?
