I suspect that the software is expecting the typical orange mask found on color negative film. This would normally be corrected for by injecting a hefty dose of blue. When the negative (with extra blue) is converted to positive, the blue turns orange.
I have this scanner, but haven't yet scanned b/w negatives with it. I wonder if the problems you are seeing could have anything to do with ICE. Though this seems most unlikely, since ICE is supposed to be shut off when scanning b/w ... Just throwing this out there ... b.
