I've checked nu door open and HR Park open and they are like you say they should be. I will try the pc obstruction when I get back out there. I also have noticed that under debug where it tells you why doors are open, it should say doors closed, then answering floor call, the Door time (briefly) , then back to doors closed. It stays on "answering floor call". That's why I'm thinking it's not properly cancelling calls completely.
