Battle for the Cup line issues

[ngummesen7]

Whenever I play battle for the cup I seem to have an issue with only a couple lines playing. if I use best lines or change them to how I want them it seems that I only have 2-3 lines playing for me. I use auto line changes. I played a whole series with just two lines. Is this a issue with the game or do I have a setting on/off that I need to change?
