It is on 6 max tables. PA Hud finds about 50% of tables and displays stats on them. Well, more like 75%, but still no stats for 1/4, so it is pretty annoying.
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. Tutorial: How to Create a Log File
