Quick pick not working (help needed) (Dying Light)

My brother and I played on the same PC with a split screen through quick participation over a local network, using the nucleus coop, then we took a break for about a week, the percentage of passage of the plot was 21%, the task was brothers-sisters. Then I go into the game, turn everything on, and my brother writes on his part of the screen, there are no matches, how is that?
What to do?
