Remove from where? Like theducks, I assume you mean on the device. And most cases I have seen of this has been because the save template was set in such a way that it generated the same file name and path for several books. If you show use the template, we can see if that is it.

There are some reasons replacing a book on a Kobo device can disappear. Or seem to. When it detects changes, it processes the book and puts it in its internal database. But, if the book is already in the database and the size has changed, it removes the book from the database completely and processes it as a new book. Some older versions of the firmware would completely remove the book from the device. But, I don't think any firmware version that has gone to the Aura did this. To workaround this problem, the KoboTouch driver in calibre updates the database with the new file size when it is sent to the device. This was fixed in calibre a long time ago, so unless you are running a very old version, it should be OK.
