Outlook calendar appointments not showing on Apple Watch 9

I had lost notifications from an app, so I went to the apple store to see if they could help. I ended up unpairing and then re-pairing my apple watch to my phone. I also deleted and reinstalled the app. Notifications work again, but now the calendar app on my watch only goes back a month ago and worse, it only shows some of my outlook calendar appointments. Because it shows some of them, I know it is talking to that calendar. Why won't it show all of them? It seems like if I had put the appointment in my calendar before the date that it recognizes as the "start" date, those appointments aren't viewable.
