REV drive is ejecting tape/disk at end of file backup

Hi there. I can't find a setting to turn off the eject of removable media at the end of a backup. I upgraded to 2011 and now the rev drive kicks the tape out each night when it's done. I do not want this to happen.
I want it to stay in and be written over if I don't otherwise swap it.

It used to do this before the "upgrade".

Thanks in advance.
Doug
P.S. There are no settings I see for this in removable media options.
