I think that your impression is right.
Why? Probably because is wasn't coded that way by the developer.
However, there is an order in which files will be mailed. The order is:
- MOBI
- AZW3
- PDF
- EPUB
Only the firs available file(extension) will be mailed. To check, just mouse over the mail icon.
If you want to change that order change the file ./lib/BOOK.php
Search for the line
$bestFormatForKindle = array('EPUB', 'PDF', 'AZW3', 'MOBI'); and change the order.
Edit: Please read the FAQ
(I usually try not to too
)
