One thing to be aware of is that Merge do not specify the size of the table in their hand history files so if you join a 9-max table with 6 or less players and have the Adjust Qualifying Tables Limits option enabled then the table will be detected as 6-max and therefore the 6-max HUD will be used.
If you always play 9 or 10 seat tables then you can disable that option (
Auto Import > Preferences, or you can use the PT-icon menu "Treat As" option to tell the HUD what table size layout to use.
