rectifying a 2007 Balance Foward transaction in Other:AFMA

[fixitsean]

How do we correct a “Balance Forward” transfer from 2007 for -328.85 in the Other:AMFA?
As stake finances clerk I helped a ward clean up their Other accounts and subaccounts. Everything is zeroed out and balances between the Other:AMFA and the subaccounts. The only transaction remaining to rectify is a -328.85 Balance Forward dated Dec 31 2007 in Other:AMFA. They don’t necessarily remember seeing it before the CUBS upgrade or before Jan 1, 2010. How do we resolve it?

I have another ward with the same problem, "Balance Forward in 2007", but they have a positive balance.
