Thanks Andrew for your time and effort to respond. It's appreciated.

I certainly have all of the patches installed. My problem apparently stemmed back to 2015/2016.

This is the first time I've put everything onto the BiaB USB HDD.

Working backwards, I eventually got back to 2015 / 2016 and added these files from my archives:

- xtra_styles_pak_1.exe
- 2016_49pak.exe
- 2016_8pak.exe
- 2015_49pak_1.exe
- 2015_49pak_2.exe

Then I ran the Cleanup Utility (each time).

After that I now have over 6000+ Styles

So it seems that What Add-Ons doesn't know about many of the paks that have been released. But it also doesn't know about missing Styles that are expected to be there, i.e. deliberately removed for testing the function.

Also, there appears to be no way to search for the string "N/A" in the StylePicker. Scrolling through 6000 Styles looking for a few N/A's is of course impractical. Too easy to miss.
