0.93.1: Categories just partly updated when editing IPTC Keywords for multiple files

[rapple]

XnView: MP 0.93.1 - 64-bit
OS: Windows 10 - 64-bit

Effect: New keywords saved in IPTC dialog for multiple files, updated partly in the database

When selecting multiple images and editing IPTC data (keywords), the categories filter not updated accordingly, only partial. For example if selecting 18 files and edit the Keywords in IPTC dialog, then clicking on "Write to all files", the categories filter tab is only updated by 16 items, not 18. I reproduced it with 5 images (updated only 4) as well. When I search for the keyword, XnView lists all 18 files, but in the categories filter there is only 16 listed. I have to find manually the missing 2 files, redo the Keyword save process (without entering again, because the keyword is already there!) by just simply clicking on the Write button. Then it is added to the filter.

To reproduce:
1. Browse a folder with more than 20 image files (JPEG format).
2. Select 18 images.
3. Right click on one of them, and select "Edit IPTC/XMP" in the context menu.
4. Add a Keyword (for example "HDR")
5. Click on Write to all files button in the IPTC dialog
6. Check Categories filter for "HDR" keyword, not all 18 is listed.
7. Click "HDR" Category in Categories Filter, less than 18 files are listed.
7. In Quick search bar enter HDR
8. All 18 images are listed with HDR Keyword

Expected behaviour: IPTC Keyword is saved to all selected images and the Categories is updated with all the files.
