New event doesn't show in calendar

Hi,
I have found this problem before in community but no solution and I think that I have found a new clue.
When I add an event on cms server it shows fine in calendar but if if login to cms admin from another computer it doesn’t show up in the calendar.
It says the event is added but I can only see it in browser on cms server.
Logged in with the same credentials.

If you create a layout in the server, can you see it with your other computer?

Yes, layouts works fine.

Ok so please try to clear the browser cache on the computer’s that not showing the calendar event.

Already tried that and both with IE and Chrome.

Are you selecting a display from the list at the top of the schedule?
