I also tried clearing cookies and to no avail, the non-selected forms get deleted, and if you import a form twice it overwrites any changes you have made.
I have made major changes to a 1099-B and am still awaiting more forms to import from Fidelity, so this is going to be a major issue.
Any relief to fix this bug coming, or better instructions on the "clearing cookies -- for a particular browser?" because that "trick" didn't work for me.
