@Thomas_AR: are you testing the templates by sending a book to the device that is already on the device? If so, then you are probably running into a calibre wireless device driver feature that prevents duplicate books on the device when metadata changes. If the WD detects a book with the same unique ID (UUID) and format already on the device then the template is ignored and the current path on the device is used.
There are two ways to avoid this behavior.
- Delete the book from the device before you resend it. If you delete the book using calibre then you must disconnect and reconnect so calibre forgets about the book. If you delete it in CC then it should be forgotten as of the next connect.
- Totally turn off this behavior by unchecking the option "Replace books with same calibre ID" in the wireless device driver configuration.
Note that if you choose the second option then you will likely end up with the same book in CC multiple times, once for each different path generated by the template.
