If you study the images attached to the original post of this thread, and also read the ToolTips in ZMI, you will notice that ZMI updates the Zotero_* custom columns in Calibre upon Importing a Zotero .csv export file into ZMI.

Apparently you are just using Calibre as a source of linking a document location in Zotero. You must not be using Calibre to store the Zotero Metadata in Calibre itself in the ZMI Z* custom columns.

You cannot expect Calibre to have Zotero Metadata unless you use the Zotero Metadata Importer plugin to first import it.

Comparing Calibre to Zotero using the ZMI plugin presupposes that you have something in Calibre that ZMI knows about, i.e., the Zotero Metadata, especially the Calibre ZMI custom column Zotero_Key value that Zotero uses to organize all of its data. The Comparison Tab in ZMI matches Zotero_Key in Calibre to the Zotero Key value for a particular item in a particular Zotero Collection.


BTW, you should download Calibre 5.99.8 from the Qt6 Beta testing thread, and use the Qt6 version of ZMI in this thread just a few posts earlier than this one.
