Order auto finalize after 17 days at which time funds are released from escrow to the vendor. If you need to extend the finalize date you need to move the order into the resolution center before the 17 days has past and request and extension, just moving the order into the resolution center adds 5 days. Looking at the timeline you posted it would appear that you finalized the order yourself by clicking on 'finalize' soon after the order was shipped.
