Teen/child sims always stuck on school vacation

Please help! My sims won't go to school and It says that they have an available vacation which doesn't show up on the calendar tho and in fact on the calendar It says that those sims should be busy with school on that day instead. First It told me that they have a vacation of 24 days available, I use mcc in my game so I tried editing It into 1 day and waited for It to pass. Once It was time for them to get alerted to go to school nothing came up the game doesn't tell them that they should go and It still says that they have 1 day of vacation available but the button for "go to school" Is there and I can send my sims off but I can't go with them and the game doesn't react in any way If I don't send them at all ☹️ I have highschool years and the problem Is that way I don't get a pop up to choose to go with them or send them alone. This started happening when I sent my sims on a family vacation for 3 days away from home and through the calendar I set a custom holiday for those 3 days and set It so that kids wouldn't go to school on those days but after the family vacation was over they never went to school again after that even tho that holiday was over. I do use mods in my game and I know that some career mods could be causing the problem, currently the only career mod I have In my game Is at-home daycare teacher which I will be taking out to see If It's causing Issues but If anyone has dealt with this sort of thing please notify me
