Desktop Notification Calendar Time is off

I’m on NC 27.0.2, Calendar app 4.5.2 and Desktop app 3.10.0. My reminders pop up at 10 minutes prior to the event saying that the event is in “-1year and 11 months”. I’m thinking maybe I have a time setting I need to adjust somewhere? Everything has seemed correct as far as I can tell. Any clues? Is this an issue with the Desktop app?
