No graduation, No traits aging up to YD, & Calendar doesn’t show school events

I am playing on Xbox and my teen aged up with no traits and there was no graduation any days after. As a teen, school events did not show up unless I clicked ‘aging off’ I tried to age up a teen in another family and had the same issues. The only way my sims can age up with traits is if I graduate early.  I do not want to start my whole family over I have so much progress. I tried to go to a previous save and that did not work. I wish sims would fix this issue I’ve tried everything.
