Help w/ Deleting a booked resource (Conf room)

[msikes]

I have a problem where a user created a recurring meeting, and booked a conference room as a reource. He deleted the meeting, all occurences. In the calendar for the Conference room, it shows it is free and clear, but if you attempt to book the room as a resource during the deleted meeting time, you are told the room is booked.

Anyone ever see this happen? The room is booked through August, and is a bit annoying (Especially when my boss wants to use it!!)
