Check the device driver for the Kindle, that the AZW3 format is selected as an option.
Are you getting a conversion error as well? Which ends in:
Code:

(names of files are using my source code, ignore differences. The general idea is "DRMError".
)
If AZW3 is not selected as compatible with your device (the default is
NOT) calibre cannot send it without converting, and pops up with "WARNING No Suitable Formats".
If the book is DRMed, it will fail to convert with "WARNING Could Not Convert - no suitable formats".
Fix the Kindle Device Driver, and check your tools configuration (or go to the source for help).
