copy edit setting - ealing brush are disappear

something change with the "copy edit setting" at Lightroom version 3.3, can I get your help to fix it please? I used to retouch all the colored photos with the "healing brush", and the regular brush, and than to duplicate the photos, and do copy and past to other edit (black and white from other photo) but now when I do "past" to the retouched photo, it do become black and white, but all the retouch and the things I did with the healing brush are disappear.

I try to check the "copy edit setting", and disable the option "tools" and "healing brush", but it not working. thank you
