Imported 1099-B creates Capital Gain (Loss) Adjustments Worksheet for each transaction

As usual, I imported my 1099-B transactions from my financial institutions. In Forms mode, this immediately created a Capital Gain (Loss) Adjustments Worksheet (called "Capital g/l adj" in the forms list) for each transaction, even though these transactions have no adjustments. This hasn't happened with previous versions of TurboTax, and creates hundreds of entries, cluttering up the forms list. Why are these showing up?
