Why does my S planner app list two versions of every national holiday?

[AC Question]

Since i installed google calender on my s4 to try it out, its somehow synched up with my s planner and duplicated all the bank holidays etc that appear in s planner's calender.

I have got rid of google calender as i prefer the S planner.

Does nyone know how to remove these duplicates, as they are super annoying!

Go to your Google Calendar (on the web) and delete the Holiday calendar. Your phone is showing holidays from its own calendar and from the web's calendar. (Something they should fix.)
