List authors by surname in libraries

I’ve used EndNote X2 and X5 for years, and now I’m on the 30-day trial of EndNote 20. The libraries display/list authors by Firstname, Lastname. I want to display them by Lastname/Firstname.

Can’t see anything relevant in EndNote under preferences or elsewhere. I’ve also searched this community and the EndNote knowedge base about the problem, but to no avail. How do I change to  Lastname/Firstname?
