Story progression not working with family

i have both mccc installed and neighbourhood stories enabled but they're not doing anything? My sim has 6 siblings and they've all reached the elder life stage without getting married, having kids, getting into a relationship etc. While my sims' cousins i never played with have kids every other week. I think it might be because I have played with them and they were marked as played until i moved them out but idk how to fix it?
