I set a desired HUD for every street (with the right options: IPoker, 6-max, Holdem, no limit/pot limit). Turned "dealer chat" and "show player actions" on. And the room interface is in English.
The live tracking seems to work because the pot odds are shown and the lines taken by the players.
Only the HUD stays on the "pre-flop hud" and does not change to "flop hud" etc.
