Can you please address what is going on with payouts form solved blocks?

Now I'm displaying the following:

Date       Round Time     Shares     Block #     Confirmed(#)     Solved By     Your Earnings

Why the change from ~0.44666868 BTC to ~0.27368875 BTC? after solved and confirmed?

Are you keeping payouts for yourself or what?

Unconfirmed Earnings: 0.00000000 BTC
Confirmed Earnings: 0.00000000 BTC
Paid Out: 0 BTC
Balance: 0 BTC
