Most kindle books use reflowable layout with content the adjusts to the user's screen. Others, such as comics and print replica textbooks, use fixed-layout. Some Kindle magazines, like Cosmopolitan, use a proprietary hybrid format that has both reflowable and fixed-layout content in the same file.
Calibre's conversion routine is designed to handle books with reflowable layout. Using it to convert books with fixed-layout often yields poor results. To work around this the KFX Input plugin has a CLI mode that bypasses calibre's conversion code and will work better for fixed-layout books. It is documented in the first post of this thread.
If you instead want to convert the book using the normal method to see how it comes out, you can bypass the error by selecting "Allow conversion to complete even if errors are detected" in the KFX Input tab of the conversion dialog.
Using either method of conversion the resulting book will still have some elements of Amazon's proprietary hybrid reflowable+fixed magazine layout and will probably not work well with e-book reading software.
