While doing some testing of the Kobo driver I found a problem that I would like to check.

The Kobo driver uses one or more columns to define book shelves on device. For my testing, I used a tag-like column and gave all books in the library the same value. Plus I gave most another value depending on the format.

A part of the testing, I removed the value for all the books. When I synced with the device, the shelves were not removed. After a lot of messing around (and swearing), I discovered the problem was that the last modified timestamp hadn't been updated for the books. And it was related to how I removed the value from the books.

The method I used was to find the column in the tag browse, expand it, select the value, right click on it and select delete. This worked fine to remove the value, but the last modified timestamp on the books was not updated.

When I removed the value using the metadata edit screen, either one book at a time or in bulk, the timestamp was updated.

So, is this expected behaviour, or a bug? Or is it just me?

Sounds like a bug. Open a bug report for it and I will have a look at it when I have a moment.
