Sorry, let me explain what is happening in more detail.

I got those books into Calibre fine with no duplicates alert. Its when I started sending them to device the trouble arose. I am sending them to Kobo Glo HD.

As Calibre processed the upload, the green check mark on left (that indicates the book was successfully sent to device and is both on device and in library) appeared. However, as other volumes below continued to be sent, the check mark in books above vanished. In the end, when Kobo processed the change, in ereader there was only 1 volume of the series, the last one sent. I checked both series folder and search whole book for this title. (I connected to Calibre two more times just to get full metadata upload).

I tried reuploading those volumes back again, and started the upload from later volume to first. The same thing happened, including that the volume already uploaded last time vanished. Basically, the last volume uploaded gets the green mark and stays while previous volumes get unchecked and not there.

I never encountered this issue before and don't know what is happening. The books are different (different volumes of the series, not same book with different editions). Only if I add some change to title (because different subtitle and series index # don't count for this for some reason), the books get uploaded and stay.
