Are your own stats correct at both tables in this case?
Do you have the player name in the Hud to be sure the stats are next to the relevant player?
Have you made any changes to your Hud profile or are you using one of the built-in default profiles?
If you see this problem using one of the default profiles please enable logging (Configure > Options) and restart PT4.
Play a few hands at two tables to reproduce the problem. Take
screenshots to illustrate, and then attach the PokerTracker4.log file from C:\Users\yourname\AppData\Local\PokerTracker 4\ (which you can access from the PT4 File menu) to a
Support Ticket along with the screenshots and the hand history files from the session.
