bought a kindle and started reading a few books. I sent the book to kindle via "Send to Kindle" online and it is in kfx format as I see in calibre. Now I have highlighted a few things in the book. When I try to convert the book to pdf via calibre (I have DRM and KFX input/output plugin), it fails the following message:

```
WARNING: This book contains PDF content. It can be extracted using either the From KFX user interface plugin or the KFX Input plugin CLI. See the KFX Input plugin documentation for more information.

ERROR: This book has a layout that is incompatible with calibre conversion. For best results use either the From KFX user interface plugin or the KFX Input plugin CLI for conversion. See the KFX Input plugin documentation for more information.

Converting book to EPUB 3
Format is fixed layout
Traceback (most recent call last):

Exception: This book has a layout that is incompatible with calibre conversion. For best results use either the From KFX user interface plugin or the KFX Input plugin CLI for conversion. See the KFX Input plugin documentation for more information.

```

What can I do to get these kfx books out of kindle with highlighted text
