Oh, you ran into the same issue I did. Those were GA tickets mislabeled as RED zone. Initially they mislabeled RED zone and the packages weren't showing up, even using the links from here. It took about 5 minutes before I saw the packages show up. They always assign "seats" to GA or RED zone GA tickets. They're meaningless.
Damn. It's still showing as the only price when I clicked on the Red Zone box just now. GA is totally fine though. I would have gone for it anyway. Just thought it would be safer in the Red Zone.
