Has anyone shooting with a 20D or another EOS digital been able to produce both a color and B/W image while using RAW + JPEG and a Tamaron lens?

I am having an interesting experience that Canon calls an "unexplainable phenomenon.

The story and image is in ATTACHED LINK.

If anyone can shed some light on this or has had a similar experience I'd like to hear from you.
