Shutdown does not unmount encrypted disk

I'm running PGP Desktop 10.2.0 Build 1672 under Windows 10.  Everytime I shutdown and restart my mounted PGP Disk is still mounted.  When I restart it is not.  Why is this happening?  I have "Do not save password" checked off in options.  I do not want it to stay mounted after I shutdown and start back up.  I have no idea how this can even happen.  How can PGP save my password???
