I have a Kobo Forma. I add books onto it with Calibre (currently 3.47.1) on Linux.

On my Kobo Forma, there are some books with info I want to fix. For example, in my Forma's listings of authors, where it should be listed as FirstName LastName, there is a book that shows up as

LastName, FirstName.

So, while the Forma and laptop are not connected, I open Calibre and find that book. I then change it from

LastName FirstName
to
FirstName Lastname


I then connect the Kobo Forma to the laptop. Then, in Calibre, I click on the Device dropdown arrow, and choose Update cached metadata on device. I eject the device. I disconnect the USB cable from the Forma.

But it still appears as
Lastname, Firstname.

I've tried updating the metadata while the device is connected to Calibre, and still the same failure.
