Hi
It seems that my issue cannot be easily solved, isn't it ? I am wondering if that may have occurred when I did Mojave and Calibre upgrades from Capitan (both major upgrades) ?
If so, how could I perform a clean install but without losing reading status. Is it possible ?
also when Running library maintenance, I get no errors but when verifying files I have 7 invalid titles(books name): what do I need to do with them ?
Thanks
