Issue with recurring Monthly-ON-6-Monday-every-1-month

Hi all

When I input recurring event with data as image then library generate recurring event is invalidate,

Also I can not get end date time when choose as the second image attachment.

Can you help me clear about the logic?


There are no 6 Mondays in any month, that it why this rule doesn’t work.
I think you need to change it to “Repeat every 6 week on Monday”
