XnView Software

I've been experiencing with the batch processing of images using XnView MP. For the moment I can select a bunch of images and go to Edit IPTC/XMP and input a keyword like "key1" into the textbox under "keyword" and click "write to all files" and all the images will have "key1" in their metadata. However, if I repeat the same process to add another "key2" to these files, the "key1" info will be overwritten, unless I add "key2" then "key1" again. This means every time I do this, it's an overwrite and not an appending. What I want is that I don't need to know what's already in the metadata, I just input the keywords I want to add, and they're appended to the files (not adding the same ones if they already exist, of course).

Is it possible?

--Edit
I figured it out. Instead of editing IPTC/XMP, just choose "edit IPTC". Then in the last tab "options", tick all three checkboxes (the first being "keep existing, append new")

you have same settings in 'Edit XMP'

I saw them, but they didn't work. Even if I checked them, the metadata is overwritten instead of appended.

"Edit IPTC" works.

See issue for current status and some details.

Great, thank you!

This problem is supposed to be fixed in XnView MP 1.8.4. Please check and confirm the bug fix here.

I updated to 1.8.4 and tested, still the problem exists. I've done a recording, hope this helps to better look at the issue.
