Fidelity still has not cleared this up. Their printed 1099-B has a column called 'Gain/Loss (-)'. What is different about the Fidelity 1099-B is that the amounts displayed in this column have not yet been adjusted for the 'Wash Sale Loss Disallowed' which is displayed in the previous column.
My other brokerage shows this column as 'Realized Gain or (Loss)' and the numbers in the column have already been adjusted for the 'Wash Sale Loss Disallowed'.
Apparently there's no industry standard practice for how this information should be displayed on the 1099-B.
