Description -- Captions "Remove entry for this language"
When multiple images are selected, and the caption language is different, if you delete caption, digikam will delete all captions in all languages.

STEPS TO REPRODUCE
1. Photo 1: Add a caption in x-default: A
2. Apply
3. Photo 2: Add a caption in zu-ZA: B
4. Apply
5. Photo 3: Add a caption in zh-TW: C
6. Apply
7. Select the three photos: CTRL + click A photo, B photo, C photo
8. In this case the language selector in the captions field shows "zh-TW" and "C" caption in the captions text field. 
9. Click "Remove entry for this language" button and press Apply button.

OBSERVED RESULT
"Remove entry for this language" deletes all caption, not just the selected one.

EXPECTED RESULT
Remove entry for this language! Only for selected language!

SOFTWARE/OS VERSIONS

Addition:
"Remove entry for this language" deletes all caption, not just the selected one, and caption of the all photos!

If photo 3 contain another caption before clicking the remove button  (example: wo-SN: test), this caption will be added to all selected photos!

Gilles,

I think we could add a "defined DEBUG" here to only have the output in the debug bundle.

Comment 4 Peter 2023-04-25 04:26:43 UTC 
The solution to this problem can be found in the Batch Queue Manager. (in the digiKam 8.x)
Metadata -- Assign Captions
Without the "Clear and Overwrite" switch, the function works as expected!
Excellent!

Question:
Why doesn't work like this by default in digiKam?
Why no "Clear and Overwrite" switch in the basic user interface?
