Updating a calendar that set the UK bank holidays as 'Holidays' in the calendar. After selecting the Special days for UK "Spring bank holiday" (31 May 2021), the 31 May is not set as holiday.
+ on the opposite, I selected "Summer bank holiday" (30 August 2021) and this day is set as holiday, but in "Special days" for UK, it remains unticked.
