Promotion Flags not being respected during Closing Stage (2 Stage League)

[FCCK]

Hello,

I am working on developing some lower leagues for the Mexican league. I created the 2nd Division with an Opening and Closing Stages, with 1 promotion position that will be defined in a match between the winner of each stage. So far everything works fine.

The issue is the following, in this division there are several B teams that are not allowed for promotion. I have set the corresponding flags. These teams should not participate in the playoffs in each stage (opening/closing). For the opening stage, it works fine. But for the closing stage, the flags are ignored and B teams are allowed to go to the playoffs and sometimes get promoted. I have been making several changes but it is in a point where I don't know what else to do. 

I have uploaded the file hoping that someone can help me learn what is wrong and how to correct it.

Thank you in advance!
