@PapyGribouille Please let us know which support you'd like: Bridge or LRC. I can move this thread to the LRC section if you'd like.
BTW, do not work in Bridge if you want to end up in LRC because LRC will not have a clue about what you did in Bridge because it was not done IN LRC. A classic example is to move a folder or images in the Finder/Explorer and find those items missing when you open LRC. That was because you did not move the folder or files from within LRC. Messing with Keywords inside Bridge for images that are already in LRC will not show the results you wanted in LRC.
So, which forum would you like this thread moved to? Rather, if you wish, you can start the new thread in LRC.
