I have just gone into my calendar app (which I can normally see mine & my families 8 calendars) The calendars are all still showing on the left hand side but all the calendars are empty except the birthday one. I check my phone and icloud and all still showing on both of these so events have not been deleted. I have re-started laptop, removed calendar sync in preferences, closed and re-opened the app but still nothing! I really need my calendars on my laptop, Help please !!!
