Deleted recurring events still show up on iPad/iPhone/Macbook Calendars

Question

Trying to view several calendars for the purpose of project management.  Here is the problem step by step:
1) If I am UserA and have  my calendar set up as Exchange or CalDav with FULL rights, I can add, delete or edit all events as needed.  I can add recurring events and DELETE one or more occurrences of the recurring event and have THAT show up correctly on my iPad.
2) If UserB sets up his calendar and gives me read access, I can SUBSCRIBE to his calendar using normal "other / caldav" subscription settings and view it properly.  No problem.
3) If UserB sets up a recurring event (lunch meeting at noon every Monday), that shows up properly on my iPad.  No problem.
4) If UserB is going to be out of town or decides to cancel his lunch meeting for some other reason, he can on his own machine (Outlook, Mac Calendar, iPad with Exchange full account) delete that event.  No problem for HIM.
5) On MY iPad, the subscribe calendar never shows anything different.  The same recurring events continue to display even if UserB has delete one OCCURRENCE of the event.  This IS a problem.  My view of his calendar is now incorrect.  Yeah, yeah, one meeting one day is not a problem.  But multiply that by several users, multiple deletions of recurring events, and suddenly the whole shooting match is out of whack.
6) I can refresh the calendar to my heart's content, but nothing changes.
7) Here's the kicker:  I can DELETE the subscribed calendar and RESUBSCRIBE to it.  This forces a completely fresh download to my iPad.  Doesn't change a thing.  The same recurring events still override ANY deletions that the user made to individual instances of the events.
In looking at the raw ICS file which I can download via a web browser, an entry might look like this:

You can easily see that the EXDATE shows a deletion for 2013-02-25 as well as other dates.  Doesn't matter.  They STILL show up on the iPad and in the Mac OSX Calendar.
I consider this a bug.  I hope an Apple employee sees and responds to this.  I would welcome any thoughts, workarounds or suggestions that could help with this.
Yes, I can tell users to only put INDIVIDUAL events on their calendar.  But, let's face it.  It's easier to put a recurring event and delete one or two instead of putting 50 recurring events for the whole year.
And, of course, Outlook displays things properly as do similar CalDav clients.

Answer 1

Exact same issue here. Individual events deleted from a recurring appointment continue to show up in Calendar (OS X 10.8.2).  Same events do not show up on calendar if viewed via outlook from my desk PC or view outlook web app from anywhere.
Clearly a bug.
