Hello Faheem Bial!
Your Profit and Loss report will only show the transactions in your home currency. I'll explain why.
Your income and expenses are always presented in your home currency even if you have transactions with customers or vendors in different currencies, and even if you directly added transactions from the Banking page. Therefore, your Porfit and Loss will only be presented in your home currency.
If you have other questions in mind, you can always go back to this thread.
