Document Editor Price

OK so I cannot remember what I did in older version 4.8.1 but I had document invoice editor always show price in euro currency no matter in what price order was placed.

In 4.12.1 if customer placed order $ and my store currency is euro, invoice editor shows $ no matter what currency I got selected, how to make it show euro always ?




$currency = $order->getCurrencyCode();

maybe this can be set to use primary currency ?
