I was recently trying to add a watermark to my LR profile and I must have hit something or shut off some setting as when I now export a photo, it exports the original unedited photo, not the photo with the edits I have made.
Under File settings in the Export dialog, choose Jpg, PSD or Tiff.
You have probably chosen Original, which will export a copy of the undedited file.
Wow, it worked and that was easy. I don't remember changing that setting in the first place, but I must have. Thank you so much for your help.
