Let me try to reiterate. Where does Lightroom change the metadata, please? Is it in the raw file you are opening in FastRawViewer? Or has the change remained only in the Lightroom internal database? Could you please verify that the raw file is changed the way you expect it, and if it is so, upload the raw file to some file exchange service (Dropbox, Google Drive, WeTransfer are some of the free ones) and e-mail the link to support@fastrawviewer.com ?
