This is acting normally. If you delete a meeting message from your Inbox, the calendar entry is also deleted. You can remove meeting messages from your Inbox by going to Tools/Preferences/Calendar & To Do/Display and put a check mark in the box that says “Remove Meeting invitations from your Inbox after you have responded to them”.
