High school years glitch

I've discovered that after some update, when i have two teenagers in a household, i could go to school with only one. The other one would have a day off and the one that could go to school, it does not show an option to follow them. 

I removed all of my mods and started a new game but the issue is still there. I'm doing a legacy game sooo this has really started to bum me out. When i started a new game the first day i was able to get both of them to school and follow them, but at the end of the day one would get stuck at school and couldn't return home, the same one also did not have the schoolday requirements/to-do list or whatever you would call it.
