Comment 5 for bug 1621539

Sebastien I have some other information for you.

- how do you add the event (using the menu, clicking on a day)
I am adding the day directly from the Calendar interface. I click on a day and add it that way. It appears I see the same problem from the menu too.

- what view mode do you use?
Not sure what you mean by view mode, but the Calendar is display a Month at a time

- do you get the issue in a guest session?
I have tried the guest session and another account on the current machine and both work, but both are set to a 24h clock. They don't have the "AM/PM" indicator displayed.

Good Luck!
