What gives......?

When I am in the Adjust Tag Information screen, I cant seem to move the song name up to the top of the list so it labels my song correctly. I searched the forums and found I need to drag the song name to the top, however when I try to it wont let me. I highlight the song and try to drag it but it wont move or it changes the highlighted area and allows me to change, copy, etc, the song name. I feel dumb, but what gives. Thanks for the help as I am new to this program and forum. :angry:

It's changed in 2.40
