Actually, it was me that made that suggestion.

-----------------------------------
In fact I have specified & customised the Kobo Touch driver.
That message isn't usually an error. It says that the kobotouch extended driver is not installed, which means the standard kobotouch driver will be used. It is only an error if you expect to be using the extended driver.

the forgoing is one error message.
Your original bug report started with this:
Quote:
I am running Calibre 7.8 on Windows 11

I have, until recently, run without problems. Yesterday I noticed that the Tag I apply to new fiction books was not being applied, The books were loaded but but without the tag.

The library contains 3917 epubs
Paraphrasing what you said, at least one tag exists for which Kobo collections aren't made. This means there is a problem with calibre creating Kobo collections from tags.

The reason for that is shown in the log:
Code:
DEBUG:    0.0 KoboTouch:books - prefs['manage_device_metadata']= manual
This says that Metadata Management in "Preferences / Sending books to devices" is set to "Manual management". It must be set to "Automatic management" if you want calibre to create collections. If calibre ever created collections then this preference must have been changed from automatic to manual.

Note that if the preference is set to manual then calibre tries to keep all existing collections, without modification or verification. I don't use this feature so I can't comment on its behavior.

Another part of the debug log says
Code:
collections_columns: Tags
use_collections_template: False
create_collections: True
This says that once metadata management is set to automatic then calibre will create collections using only the tags column, which given your original message is what I think you want.
