@Peter - the only workaround I found was that you could let the brick die "naturally" (i.e. run it until it falls below 11.5V), and the camera would switch correctly. Not sure if this is great for your bricks longevity though.
Definitely file a support ticket, particularly if you're seeing it with a Red-branded battery plate. One of the obstacles to getting this nailed so far has been that there have been third-party products involved.
