I think you need to save the metadata to the file before transferring them with the caption. Try selecting the files with the captions in the Organizer and then choose the File>Save Metadata to file command. (Or use the keyboard shortcut Ctrl+W).
Hi @grel , I am from Adobe localization team. We tried the scenario on German language with german keyboard and we were not able to reproduce it. We followed the below steps. Please confirm if the steps look fine to you:-
1. Launch Organizer 2. Open any Image 3. Add caption 4. Click save metadata from File menu 5. Select same image and the click edit 6. edit in editor and save the image 7. Create a new catalog and then open the same image 8. Observe caption will appear
