Description Peter 2024-01-03 19:14:51 UTC 
SUMMARY
***
digiKam 8.3 treats files as if they were read-only. digiKam 8.2 writes the information to the files, but digiKam 8.3 does not. digiKam 8.3 always creates a sidecar file.
If you add information and press the Apply button in digiKam 8.3, then add plus additional the information and press the Apply button again, the entered information will be deleted from the input fields.

Here is a short video about the problem: https://youtu.be/PIUuEWKpjGI 
-- The correct behavior of digiKam 8.2 in the first half of the video
-- Incorrect behavior of digiKam 8.3 in the second half of the video
-- The environment is the same in both cases.

Environment:
-- Linux Server
-- Database: MySql
-- Sample File(s) right(s): -rw-rw-rw
-- digiKam version: digiKam-8.3.0-20240103T112058-Win64.exe (Qt6)

Settings:

Comment 1 Peter 2024-01-03 19:50:26 UTC 
Tested in the digiKam-8.3.0-Qt5-20240103T113356-Win64.exe too.
The Qt5 version is works well.
Comment 2 Maik Qualmann 2024-01-03 21:20:32 UTC 
The cause is probably a current test in digiKam-8.3.0 as to whether we can work with Exiv2 in UTF-8 file names. However, as it turns out, it doesn't work. I see that you have non ascii characters in your path.
