Thankyou for your reply.
I did as you suggested and followed the instructions in the wiki. For the exercise I stayed with using myshelves, My Shelves as shown in the wiki.
I attach a zip of screenshots of setup of the new column and plugin settings.

I then selected 124 epubs to be sent to the device. All of them had the same metadata, ie. Author, series and custom metadata.
Of the 124 files, only the last 2 are sent to the device, and they are renamed to
#myshelves, series.epub and #myshelves, series.txt as separate files with no author.

The Kobo drivers in Calibre are
Kobo Reader Device Interface (2.3.3) by Timothy Legge and David Forrester
Communicate with the Kobo Reader

KoboTouch (2.3.3) by David Forrester
Communicate with the Kobo Touch, Glo, Mini, Aura HD, Aura H2O, Glo HD, Touch 2, Aura ONE and Aura
Edition 2 ereaders. Based on the existing Kobo driver by Timothy Legge and David Forrester.

My Kobo in the Kobo utilities shows as a Kobo Aura, Version 3.18.0, not as those listed.
Might this be the cause of the problem ? Or have I got something completely wrong ?
Calibre version 3.33.1
