While you are seeing player names at the tables the player names in the hand history files used by PokerTracker 4 have been
anonymised by partypoker to 'Player 1', 'Player 2' e.t.c. As a result PokerTracker 4 now defaults to show session stats for the anonymous players but it will still track your own results fully (your own name is not anonymous in the histories). The anonymous names only apply to normal cash tables; it doesn't affect tournaments or fast forward tables at this time.
