Hi again
Did some tests, as far as I dared to go
I use send to device plugboard to add series info to title when sending to my K3. When importing books into new, empty library, the books are imported, but title now includes series info if book is on a series.
If book is in a series (and included in title), then calibre does not show the book as being on device.
If i change the book title back to the original (remove series info), restart calibre, the book shows as being on device !
Does this help ?
Waiting for info from you, misling
