9 seat tables should work correctly.
So in the 888 software you are not always shown in the same seat? You just appear in whatever position you sit down at? In that case, make sure the Preferred Seating option is set to "None" for all table sizes in PT3 > Auto Import > 888 Poker Configuration.
Open a single table and when the HUD appears right-click-drag the stats to the correct places. Once you have them where you want them click PT-icon > Save Layout.
The stats will then appear in the same places at any tables of the same type that you open in the future. You will need to do this once for cash and once for tournaments.
If you still have trouble after that please
report your problem and attach the hand history file and
a screenshot to illustrate along with your log files.
Thanks.
