Hi Andras,
thank you for reply. I am attaching requested screenshot.
There are other things I tried:
I tried ending the recurrence on Friday, November 4th and starting new one – did not help.
I also tried to end the recurrence on Friday the 4th, skipping the whole week and starting new one on Monday the 14th.
In both cases the calendar keeps adding the event on Tuesday and other classes get messed up.
