I occasionally play Zoom heads up on Stars and sometimes versus some opponents, my opponent's stats will show up as what appears to be 6-max or full-ring stats instead of heads up. Their small blind and big blind vpip will be in the teens or low 20s and when i double click to get session stats, the correct stats seem to show for a 1/2 second and then *VOILA* it automatically switches back to the 6-max looking stats even though it should show the session stats only.
Not sure what's going on, but I've had the same thing happen once before in the replayer. Heads up stats showed as much lower than what they could possibly be. Something weird happening here.
