Identifier Kobo Metadata intrusion since 7.24

Mich06 · 01-12-2025, 05:32 PM

Hello,
I just updated Calibre to 7.24, and I've noticed than all books having an ISBN identifier in the metadata windows now display some sort of *phantom* identifier named "Kobo Metadata" appearing in the Book Details panel (but not in the metadata window). When I click on it, it sends the isbn number to the Kobo site (resulting in an error in Kobo site).
I have the Kobo Utilities plugin. Is this a bug due to some kind of new incompatibility with it ?

↑ ↑ ↑ ✔ possibly/probably.

Try running with no plugins - there's an option in the Preferences drop down menu, viz:

I just did. Zero plugins. The phantom id "Kobo Metadata" is still here, duplicating systematically the isbn identifier in all files. It appears only in the Details window, nowhere else...

I really don't understand what's happening.

It's from the Kobo Metadata plugin. Ask about it in the Kobo Metadata thread.

Yes, it was.
After deleting the Kobo Metadata plugin, and restarting Calibre, the problem is gone.

What is strange is that the problem appeared only in Calibre 7.24, not before.
Maybe it's related to the new feature : "Add from ISBN: Add a checkbox to automatically convert obsolete ISBN 10 to ISBN 13" ?
I'll check the Kobo Metadata thread.

A great thank you, anyway !
