[running Calibre 4.70 on Windows 10; auto-conversion from EPUB to KEPUB enabled via KoboTouchExtended plugin]

I believe this problem has a very simple solution but I couldn't find it anywhere on the Internet.

I have 5 couples of 'duplicate' EPUBS: in every one of them the ebook was published by two different publishers, and this is correctly detected by Calibre.
However, when I select all ten ebooks (i.e. the 5 couples of 'duplicates') and send them to my Kobo, only one copy per couple will get to the device.

And if I select the 5 'un-synced' ebooks and try to send them again to the device, Calibre will start the operation to convert them in KEPUBS, but the transfer will fail again with no alert appearing on the screen.

This behaviour is different from other instances, where Calibre recognizes two ebooks having the same title or being identical and asks me whether I want to add the ebook anyway or to cancel the transfer.

How do I fix this?
