What you have looks correct. And it is working here. I had to test as I don't display the column and I realised I hadn't looked at it for a while.
Could you run calibre in debug mode and post the log? That way I can see what is happening. To do this, right-click the preferences button and choose "Restart in debug mode". Calibre will restart. Connect the ereader and do a store for a couple of books. Then close calibre and post the displayed log. Or send it to me in PM.
