Players listed as probable DNP or if they play, they only play 4-7 mins the whole game.

Listing them as probable still indicates they are injured but able to play if so desired as opposed to players listed as out who cannot play. That does not mean they cannot receive a DNP or very low minutes. I would suggest that if they only played like 5 minutes they probably should have been a DNP totally but there is not a bug there with them being listed as probable but still held out.
