The 311,000 (currently 309,500) is the top of the bid due to a time stamp of 8:47:03. Next is 1,000,000 placed at 9:38:50, What you see on bid ask is the sum of all bids at that price but it seems to max out at 499,500 for some reason. The ask of 96,000 @ .21 is the sum of 5 orders at that price (53,500 + 17,000 + 20,000 + 4,000 + 1500). That number displays properly and I can only guess it's because the total is less thn 499,500.
