Issue when Aging Down Sim

Hi there!

sorry if this is a dumb question but my sim had 3 kids, two of them were twins and long story short, I aged them back down from YA to teens. Both sims were married and one of them had a degree from university. When I aged them down using CAS, it still showed they were married to their spouse (who I also aged down) and the education still shows my sim has a degree. Is there a way to reset my sim to get rid of this and start them from teens without losing the relationships with the family members?
