How do I remove holiday markings for a whole country?

[Lion_King]

By mistake I added the holidays for the same country 3 times, and now I can`t
remove them. I go to Add Holidays in the Calendar Options, but removing the
tick doesn`t help.
I appreciate any help!

Display the calendar by categories. Delete the entire Holiday category.
Start over.
