My Townie Teens Don't Age?

Went to play my high school years save when I noticed Wolfgang Munch was a student. His little brother Lucas is already young adult and for some reason he was still a teen. I checked around school and most of the other students were at 37/24 or 50/24 days for example. (My age setting with MCCC is 24 days) I have noticed that all of the affected teens were homeless and that teens that live in a house seem to be fine. The issue is that HSY creates homeless teens/families to fill roles and its immersion breaking that sims' younger siblings are now older than them and homeless teens can never age up. I added one of the homeless families (with 2 affected teens) to my played households and loaded back to lot they were on with my sim and they both aged up,  but this fix shouldn't be necessary.
