I recently got a Kobo Libra H2O and went back to managing my device with Calibre. I'm running into an issue with updating collections on the device where I'm not sure if I'm doing something wrong, or if what I'm trying to do is impossible.

I have my books tagged both with genre and a "to read" tag. I.e. my Example Title will be tagged "mysteries" and "mysteries (to read)". I've customized the Kobo Touch plug-in to create collections from "tags", and this is working. When I've read Example Title, I remove the "mysteries (to read)" tag on Calibre. Then I want to send the edited book to the device again to update the metadata.

On the device, however, it stays in the "mysteries (to read)" collection. (Similarly, when I renamed a tag in Calibre to correct a spelling error, sending the library to device created the new collection with the correct spelling, but also kept the old collection with the incorrect spelling, even though in Calibre, there are no books with that tag anymore. I do have "Delete empty collections" ticked in the plugin settings.)

Am I doing something wrong, or is updating collections on the device that includes removing, not just adding, simply not possible? (I had a Kobo Glo HD a few years back and I *thought* this was possible, but I may be misremembering.)
