Meeting reschedule not updating original calendar entry

Hi, we are currently in the process of upgrading our domain to 8.5, some on Windows, others on Linux Red Hat. I have an issue with one user. He sent out a meeting invitation to 2 people, they had accepted. He then changed the location of the meeting and a new invite with comments was sent out to the 2 people, they accepted this, but the original calendar information was not updated with the changed location. If either of the people went into the original meeting reminder in there calendar, they are prompted that some details have changed and did they want to update? Is this normal? I would have expected the reschedule acceptance would have changed the location in the calender entry?

Subject: can you reproduce

could be a 1 time issue with that 1 meeting. Can you create a new meeting and reproduce the issue over and over again or has it happened just this once? If you cannot make it happen again then there is no way to tell what really happened.
