Sounds like a bug, but just to make certain, try this:

Stop alsa

sudo /etc/init.d/alsa-utils stop

Delete the alsa configuration  (this is saved from current in memory
values every time alsa-utils stops, so you must stop alsa first)

sudo rm /var/lib/alsa/asound.state

Then reboot your system, and see if the values are still funky.
