Before i did the image cleanup, I thought that I had only 1 copy of the book - with a cover. I've attached an image of how it looks now in a search.
I have done a database backup when I have made changes recently, so if I restore the version before the image cleanup, will that fix the problem?
In Calibre, under "on device" most of my books show a green tick and "Main (2 books)" while the Kobo is connected
