Duplicate Key Error in Currency Translation Window

When I attempt to load "Historical" Rate Type in Tools, Routines, Financial, Currency Translation, I receive an error "Cannot insert duplicate key...".  The error references a Journal Entry number and account index for Retained Earnings.  There are 2 Retained Earnings transactions having the same JE Number referenced in the error with Source Documents of BBF and P/L.  The error only occurs on Closed Fiscal Years.  It populated the screen for the open year 2011, which also has 2 Retained Earnings transactions having the same JE Number and with Source Documents of BBF and P/L.

Thanks,

Ray
