Still can't see Account Name column in Activities

Still can't see Account Name column in Activities

Hi,

I submitted a report yesterday that the Account Name column in Activities went missing.  I received a reply back from Prakesh saying the problem was fixed, but I still can't see this column in my Activities tab.  I tried selecting "edit" to my view and adding the field but don't see it listed as an option to "drag over".  

Thanks,
Angela
