Missing Game Data?

So being one of your fans for three years now. And I love your work, it's allowed me to come along ways. However I noticed that your PS2 roms lineup has empty data apon extracted data. Is there something I'm not doing or doing wrong? I have tried 7zip, winzip, winrar and two or three browser's. Best of luck to you guys!
