Are these your own custom stats that show "--" or are they from a purchased package? Make sure you have the stat files installed correctly in the Hand2Note\Config\Filters folder and that you have active license for the package if it's the commercial HUD.
If these are your own stats, make sure the settings are correct and they all return hands during the test in stats editor. Check that game types are correct and you have enough sample size for them. Rebuild stats again as shown in the linked instructions above
