Holidays not shown in calendar

Hi, I’ve just imported my local holidays into my calendar but they do not display, what could be the problem?
Thanks and regards.

Make sure that the calendar is checked on the left pane.

 

Hi, I’ve checked the calendar and it still doesn’t show the holidays.

I am having the same problem.  Followed the same process / instructions for Canada; checked off boxes; nothing shows up in the Calendar.
