What sir? Your tables need update to make sense.
It means that every 7 days you play you'll get a Seal. But if you never miss a single day of attendance, you'll get diamonds on those Golden days (not sure if they'd go along with the seal, or a replace them)
Edit: After checking in-game, it seems having a perfect attendance means you get the Diamonds instead of the Seals.
Also extra things I noticed:
* Searching in the Auction House now is done inside categories. This means that you can't search for a Serenia's Necklace if you're in the Weapons category, for example.
* The original post doesn't make it clear, but the Santa donatios require "Shining Wrappers". I believe donating any of the lower tiers won't help getting the buff.
