Please try to do this in QB 2022 that has been downloaded two hours ago.

1) create new item

2) create new vendor with currency EUR 

3) Make sure thare is a currency rate other than 1 to 1 for USD-EUR

4) Create a PO on this vendor and item

5) Receive the item on the PO

6) Create bill on the receipt (since PO-number is gone for a year now)

Please look at the EUR amount on the bill. It most likely will used the USD amount as the EUR amount and multiplies the rate with that amount to calculate to USD, which basically is multiplying it twice.

Now do the same again but create the bill before you receipt the items. Then it looks okay. However, when you receipt the item, it again uses the USD amount as Euro amount and multiplies the rate twice
