Meeting Organizer Defaults to wrong person

We have a public folder for our conference room calendar to schedule meetings
in. Everyone has access to this calendar and can schedule meetings. They are
to be the organizer and invite themselves so it shows up on their personal
calendar.

Yet some meetings have been schedule and the person doing it, is not listed
as the meeting organizer in the Scheduling tab list of attendees, but someone
else, someone who isn't even involved. How is this happening?

Also, with some other meetings, when the Scheduling tab is viewed, the
meeting organizer switched to the person viewing it at that time. What is
happening here?

Thanks in advance.
