Finder not showing DVD/CD drive even when it is checked in the Preferences

Question

I am playing a DVD so it's definitely "understood" by macOS to be present. But not by Finder ?

I tried unchecking and re-checking the CDs, DVDs and iPods: no change. I have also rebooted the system a few times: the behavior persists. What can be done here? I am on Catalina 10.15.3

Update The DVD drive is found without any issue on the command line: the following works:

diskutil eject /dev/disk2 .

From comments, it seems like a simple 'wrong pref'.

The pref in the posted image is for Desktop visibility.
To show in the Finder sidebar, the one required is in the 3rd tab, Sidebar.
