Is there a way to reinstall Calendar, from the App Store or something (didn't see it there). It's acting weird, each day has two dates at the top, on the right is the correct date, and on the left is some other date. (It seems like it's reading two months at once or something).
I haven't been able to find out how to reinstall. thanks!
