You have customised the driver and specified collections, undo that and you should be fine

I did what? how does one go about undoing that? pardon my ignorance

What OS and version are you using?

macOS 15.3 and calibre 7.24

this is what I got from: starting up calibre, turning wireless connection on, connecting my device (after many, many attempts though), and finally ejecting it. Does not seem very verbose though.
