Not sure about that block, there are only 11 confirmed blocks and 2 orphaned blocks on the pool.
the block numbers are as follows.
confirmed: 397046, 394879, 394909, 397031, 394881, 397683, 397903, 397912, 395387, 394908, 399119
orphaned: 396733, 397581
I am working on some code to have these stats displayed on the pools webpage.
So as for block number 399220? not sure.
if you visit the block explorer for the pools wallet address you can see what blocks are from "Coin Generation" and the other blocks numbers are just the blocks in which the payments have been processed within.
http://crypto2.net/dem/address.php?chain=1&addr=Ni6Ajbp2G5Q3cchzL1aDH61qy8PKJH5KtAI have the stats for block 399119 which was the latest block found

which shows the shares for that block, it shows you have about a quarter of the total shares for that round about 12.5DEM which is apx. what you received.
Hope this clears it up. Hopefully next block you find, you are on your own...
