After I upgraded it looks like the Foreign Exchange Rate gains (and losses) are not calculated anymore.
My Billable Expenses are not 0 anymore, while they used to be 0.
I don’t see any items for those anymore in Foreign exchange gains (losses)
I was able to reproduce this on a new business
Steps to reproduce
Add Expense Claim Player in settings
Add 1 Foreign Currency
Add Exchange Rates
Add Expense Claim for Payer 1, Account Billable Expenses -> Customer on 31/7/2020
Create invoice for this customer for uninvoiced items on 2/8/2020
The billable account looks like this now:
The foreign exchange gains (losses) are Empty
The 200 CUR is invoiced on 2/8/2020, and the Exchange Rate 3.1 is applied.
But is only credit this amount from the Billable expenses account.
Previously the Billable Expenses account was leveled and this resulted in a loss on the Foreign exchange gains (losses) account.
I could not found any solution to level my Billable expense accounts with additional journal entries.
