Busy and Tentative not reflecting on all calendars invited

Question

Our sales team has a unique issue which I'm not quite sure whether it's an expected behavior or is something misconfigured.
Example:
- Becky is a delegate for room resource "Board Room" and "Auditorium"
- Becky has Owner permission to room resource "Special Events"
1. In Outlook 2013 Becky adds an appointment to Special Events and then adds the 2 other rooms as "Resources".
2. Manually set Show As to "Tentative"
3. Save & Close
4. She receives 2 approval requests because she's the delegate.
At this point she can approve Board Room and Auditorium and those 2 appointments will become "Busy" but the appointment in "Special Events" will remain Tentative.  If she manually changes it to Busy, 2 new approval emails get generated
and those other 2 meetings are now set the Tentative (by design).  Obviously if she accepts them they'll both become Busy again.
The issue is there's a disconnect between the Special Events's busy/tentative to the other 2 delegated room's busy/tentative.  Is this by design or is something configured incorrectly?
As a separate test, I send a meeting invitation to her 2 delegated rooms and manually mark it as tentative before sending.  Once she approves both invites, we now have a situation where the 2 rooms will be marked busy but my own invite
is tentative.
Thanks

Hi,
If the original meeting request is marked the items as Tentative instead of Busy status before sending, when the attendees accepted the request, the meeting should also be shown as Tentative in the Calendar. It would not be changed to Busy.
Please check whether the issue happens to other rooms which are set with delegate. Also run the following command to check the calendar processing for two rooms:
