Missing Class - DU

my sim is sorta missing class but not... so last night i was playing and my sims has a class that starts at 1:30 and ends at 2:55 and right after another class from 3-4pm well my sim wasn't getting the pop-up that class was in an hour till after the class and I didn't get the option to go to class either but at 2:30 my sim got the pop-up and was able to go to her 1:30 class but was instead there from 3-4:55 and would then go to her 3 o'clock class.

I mean i'm happy she's not missing classes but she also had a full-time job in the culinary career which she was missing as her shift started at 3 and she was in her class cause the time is weird. I ended up changing her to a freelance career cause all her free time was being taken up by classes that she should of been at earlier than when she was attending them.
