Faders up on wing when connection is lost

Hey there, i have several PlaybackWings - the old blue ones with just 10 faders - that i use a lot.
i just noticed the following: when the wing looses connection to the console (which happens occasionally because power and usb-connections on the back of the wing are a bit shaky) all the faders go up to 100% by default.
changing that in the virtual faders tab has no effect whatsoever...
dangerous to have smoke-machines on these faders and leave for lunch ;-)
Why can we not change the default fader-behaviour here?
or is this a bug of my wings?
