Help please.

I have always been able to go into a song and go into sorting and make the song title look the way I want it to look. For example, I just bought the song The World by Brad Paisley. After it downloads it shows up in my list all the way in the W section instead of the T section. I have always been able to go fix it by going into sorting and adding The in front of the other words so it shows up in my itunes alphabetically starting with The. For some reason I can't do that now. What am I doing wrong?
