Hi,
Don't worry ; we are professionals and we know our IP (and we also know a lot of different method to retrieve it).
Please provide a screenshot to illustrate the issue.
The Paypal pro did not have any single modification for that part in the last 3 years.
So I don't think that your issue is related to the Paypal Pro plugin (unless it has been modified manually).
'CITY' => @$order->cart->billing_address->address_city,
$vars['SHIPTOCITY'] = @$order->cart->shipping_address->address_city;
