Calender week number

I have week numbers in my iphone11 calender.

Last year there were 53 weeks and because of that my calender now shows the weeks one week ahead (f.e. today the 27th of May is week 22 in my calender - not week 21 as it should be)

I have tried to remove week numbers, restart phone and apply week numbers again - nothing works.

How can this be corrected?
