When you use an external editor, the resulting image is no longer raw...so it's natural to have Embedded as the only profile. DNG profiles are for raw files, not rendered files. As for the lens profiles, it's not clear what you are saying...on a raw file unprocessed, you are seeing all the Nikon lens profiles and after rendering you are not? Again, that makes sense because there are two kind of lens profiles-those made to process raw files and those made to render JPEG or TIFF files. Raw lens profiles are different than rendered files...you need to do the DNG and lens profiles BEFORE rendering images to an external editor...
