FX rounding errors with Generate Draft Invoice Process causing AutoInvoice errors

I have an operating unit with a functional currency of GBP. Project currency is USD, invoice processing currency is set to Funding Currency. When the generate draft invoice process is run, it is creating FX rounding errors. I found a Metalink note stating that checking the Invoice Bill by Transaction Currency box would resolve the issue. It has not. It did calculate a different amount, but not the correct amount in USD. I am in the middle of a UAT and would appreciate any suggestions. I am also opening an Oracle SR. Below is the sample data from the invoice.
