Changing Customer Bill To changes the Bill To for closed invoices

We recently found out that if you change the Bill To information for a Customer, QB also changes the Bill To information for sales orders and invoices to this Bill To information even if the Sales order or invoice has been closed. For example, an invoice was sent 2 years ago and paid but if I change the Bill To, it changes the Bill To of this invoice from 2 years ago. This should never happen. How do we stop this?
