Well, my initial guess was right. I need that date entry to be able to make a sensible list. Your publication list needs to be sorted somehow. The only way to do that properly is to use a full date. As I suggested just click any random date if you are not in the mood.
I can spend two evenings to work this out…but then next month I will have to rethink it all again because new publications are not appearing at the top of the list.
Sorry, this is one I am going to leave for now.
