Can't select snooze time in ical events

In Lion, the notificacion of ical event give the option to snooze it in 15min, 30min, 1 hour before, etc. Now in Mountain Lion, all ical notification goes trought notification center. The thing is that now it only shows me the option "snooze" but it doesnt give an option to snooze it in "....". Any one knows a fix to this?

Thanks
