Please update to the latest PAH version
1.19.10 if you aren't already.
Make sure you have the right setting for your pokerstars table type in Layout Manager -> Options.
If you disable preferred seating in both PAH and Stars, are your stats arranged correctly? Make sure you get it right like this first, then re-enable preferred seating in stars and configure it in PAH. Make sure you configure it for the correct table size - it's easy to mix up 9 and 10 seat tables.
If it's still not working after you start playing and the first PLAYED hand has been imported, Please enable logging, reproduce the problem on a single table and play 30+ hands, and send the PAHud.log file via the
Support system so that we can review your configurations and troubleshoot the issue.
