In PokerTracker 4 click 'Database -> Database Management', click your database then 'Rebuild Cache -> Full Cache Rebuild'. If that does not fix it then please turn on 'Enable Logging' in PokerTracker 4 via 'Configure -> Options', restart PokerTracker 4 and reproduce this problem you are describing. Next create a support bundle via the 'File -> Create Support Bundle' menu option in PokerTracker 4 and then attach that to a
Support Ticket where a technician can review your logs and advise you accordingly.
