Hi,
I am embedding font in AZW3 format for correct presentation on Kindle.

It nearly works; looks perfectly fine on Calibre e-book viewer but renders with extra spaces on Kindle Paperwhite and older Kindle.

See attached first line, second word: "kahwha:" vs "kahw ha:"
More examples below if you look carefully at screenshots.
The font itself renders just fine.

AZW3 file is attached together with screenshots. What I'm doing wrong?

PS I've tried couple of other fonts and result is exactly the same.
Thanks a lot for your help!
