I fulfilled a number of purchased ebooks in my library on ADE 4.5.3 for Windows using .acsm files.
Due to some complications I mistakenly imported a number of these .acsm files multiple times.
The result is that the books now appear multiple times in my library.
Although I have tried to delete the duplicate entries from within ADE, they always reappear the next time the library syncs.
Is there any way to remove them permanently?
Thank you very much in advance.
