I was filling the new Kobo. Once or twice Calibre crashed. So, I transferred less books at a time. Unplug/plug to let Kobo add the books.

After all that, I saw that I had Collections but all empty! I checked the books on the Kobo in Calibre. Every books had it tags in the metadata, but not visible in the Collection row.

Not sure what went wrong.

Maybe I should delete all books on the Kobo and start again.
The collections are stored in the Kobo server. But, it does not store anything about sideloaded books. It will sync the the purchased books that are in collections to the server. When you setup a new device, Kobo will sync what it know about the collections to the device. That means if you have only sideloaded books, it will create the collections and they will all be empty.

But, assuming the configuration is correct, calibre will do the collection management each time you connect. And if you are sending new books, it will create the collection entries as the books are sent.

If what you have done is to put the sideloaded books on the device and then log into your Kobo account, then you will get empty collections. Calibre should fix this on the next connection. If it doesn't, the most likely thing is a configuration error. And I'm serious about that. I don't know when the last time someone actually found a bug in the collection management was. The next most likely reason is a corrupt database. But, calibre would probably show an error for this. The next reason is that the books on the device are not matching to books in the library. But, any books that have a green tick against it will have collection management done for it.
