If the setting does not match the current default then that indicates the book in question was converted sometime previously and the conversion settings for that book were locked in at that time. You can press the "Restore defaults" button at the bottom of the conversion dialog to discard the settings from prior conversions.



It only respects the default preference if that particular book has never been previously converted.

huh. I have been wondering what the OP is doing that I'm not because I've never seen that behavior. But quite a while ago, I set my preferences to make all books epub first (better for working with on the PC), and convert to KFX ebook only to put on my Kindle. I'm constantly taking stories off once read, then they update and I put them back on as newly converted KFX. Which behaves properly as it keeps the ebook default. would it make a difference that I have Calibre delete the KFX file when the story is updated? Would that wipe out any 'wrong' lingering conversion preferences? or is it that the way my process works (epub ->kfx ebook ->kindle)I don't have the 'wrong' preference ever set?

Deleting the file created by conversion does not revert the conversion preferences to their default values. I assume your process works bedause you have the defaults set the way you want them before converting a book for the first time.

FWIW: Whenever a book is converted the conversion settings used are stored in the database regardless of whether they are specifically set or the 'default' settings in Preference are used.

The template function has_conversion_options can be used to interrogate, I use it to set a column icon:

Problem Description:
When using the Calibre plugin KFX Output to convert an EPUB file to a KFX file, an error occurs with the following message:

calibre, version 8.15.0
Error: KFX conversion failed: <p><b>Cannot convert test</b>

<b>Conversion error:</b> Enhanced Typesetting not supported for this book</p>

After testing, it was found that this error occurs when the EPUB file being converted contains CJK extension characters with Unicode codes such as "2E8A9," "322DC," "322D5," etc. An EPUB file is attached for reference. We hope you can resolve this issue. Thank you very much!

KFX Output, version 2.18.0

I tried your book and it works for me.

Most of the conversion process is performed by Amazon's Kindle Previewer. Any version of the Previewer 3.54 (released in June 2021) or later should be capable of converting that book.

If you are using an older version you will need to update it. If you are using a more recent version then please post a log from the conversion and I will investigate it further.
