Apple Watch smart stack calendar widget shows all my events start at 12:00

I recently updated my Apple Watch Series 10 to watchOS 26. Calendar widget started to show all my events start at 12:00. When I click them or open Calendar app, I can see the time is correct. Notifications comes at correct time. I can see the Calendar widget in my iPhone is correct as well. Only the widget in watch is broken.

I tried to reset syncronized data, turned calendar data off and on for all my accounts and none seems to fix it. I didn't want to reset the watch without knownig that it'll work. Any idea why might this be happening?
