Hi, Thank you for the reply, I think what has happened is during one of Calibre/plugin updates, my device settings have reverted to the native Kobo/Calibre (Set Series Information ticked) and as you have said, the series information has then been transferred to the device.
I don't know if all the Kobos use the same book display format, but on mine each book has a cover image, then three lines:
First Line = Book Title (modded via plugboard or not)
Second Line = ****
Bottom Line = Author
On my device:
Using the native setting with Set Series Information ticked, sets the second line to be Series Information - if the title is longer than the space available on line 1 it is then truncated
If I stop using the native settings (untick Set Series Information), the second line is then available for the remainder of my title.
My personal preference is to include the series in the plugboard title, not use the 'Set Series Information' but be able to see the entire title as it rolls over to line 2 - unfortunately, while the series information gets transferred on connecting the device, it does not seem able to undo it without removing/readding all the books.
Thank you both for the replies, I appreciate the efforts
