I have discovered a problem with completing repeating events in my calendar.

Like many people I have a number of repeating events in my calendar, such as the reminder for the medication I take only on Sundays.

I have noticed that if I simply open the event on the calendar and tap the check box to complete it nothing seems to happen but if then tap the back arrow (top left) and return to the calendar it now shows as completed. If I tap twice the green "tick" appears but when I look at the calendar I find that every instance of the event now shows as completed, clearly undesirable if I want to be reminded next Sunday to take my tablets!

There does not seem to be the same problem when using tap and hold to bring up the context menu.

I am now aware of the problem and take care when completing events, but I feel that this should be looked into in future updates.
