 If rather than going to 
Preferences | 
Saving books to disk and changing the template there you can go to 
Preferences | 
Plugins | 
Device Interface and find the relevant plugin, you can do a 
customize plugin there and change the template there with no error. 
(Or with the device attached, you can 
right click on the 
device icon in the menu and select 
Configure this device and change the template there).
