Sims4 Calendar Overlap?

My entire sims calendar seems to be all wrong. I have played with my current household for awhile now and I finally decided to look into why I haven't been able to follow my sims to prom. Prom is not on the calendar at all and the cheerleading/football events are all over the place. Currently, I only see one cheerleading event (on a monday) and can only see 2 football events (on two different days). I'm pretty sure that this is because of the events overlapping, but this used to not be an issue for me? I don't see any of the cottage living events either and most of the time the events are covered up by Snowy Escape festivals or Talent Showcases. Sometimes there is supposed to be an event on the calendar, but there is just nothing at all. The only time I got the prom event on the calendar was when I turned off aging, but it only appeared once at the end of the calendar. I don't know what to do about this. I checked my mods and asked multiple servers for advice.
