Partypoker recently made a change to their tournament hand histories which caused an issue with blind levels of 1k+ (these hands were imported with a blind value of zero) and this was resolved with the release of PokerTracker v4.15.1 however you are still using PokerTracker v4.15 and this is likely reason why those statistics are not working for you. After
updating PokerTracker 4 you will to need to
purge the affected tournaments from your database before you re-import them (Play Poker -> Get Hands From Disk). By default PokerTracker 4 moves your processed hand histories to your \PokerTracker 4\Processed folder which you can access via the 'File -> Open User Data Folder' option.
