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.

What am I doing wrong?

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