Calendar Item shows as accepted even though Resource Calendar declined it

[adityar12]

I'm trying to use Zimbra for Scheduling Conference Rooms in my office. I'm facing a few issues. First off, if I create an appointment and add the resource to my Location box, the appointment doesn't show up in the Resource's calendar. Instead, I have to add it to the attendee list for it to show up on the Resource's Calendar.
If there is a conflict, the Resource automatically declines the appointment and it shows as such in the Resource Calendar. But in the user's calendar, the appointment still shows as accepted. How does the user know if the resource has accepted or denied the appointment if I'm only using the calendar feature of Zimbra and not the mail.
