While generating the report, I encountered a major problem and I cannot cope with it.
We have our orders / invoices according to the client in different currencies (dollar, euro, Czech crown). If I make an invoice report, see the picture, then the report should be in dollars because the invoice is in dollars. Unfortunately, the dollar will be converted to the Czech crown 
However, it is strange that the sum of rows shows the Czech crown instead of the dollar, but the value is correct in dollars. Therefore, only the line of line items is recalculated, but the totals are correct (if the currency designation is omitted).
Any idea what to do with it? Thank you very much for any advice.
