cgos pass issue

I am not sure I broke it, but I do not get all opponent stones killed in some games. I tried to understand the logic behing passing but it is really difficult for me, so I hope you can have a short look at this:) Maybe this has to do with oakfoam sometimes playing passes in the middle of a game without sure win...

The game is attached, here is my configuration
