ghost book issues Digital Edition

Hello,

Sometimes, ebooks I borrowed and returned months ago reappear (the cover is often missing, but not all the time... a little "cloud" glyph appears in the upper left corner of the ebook). If I try to delete them by right clicking and selecting "Remove from Library", they do disappear, but next time I start the application, they come back again.

I saw that this situation was a bug in 2016 but 4 years later, no changes ! Do you know why or what can I do ?
