I just tested this on a clean master install with Concerto data, but I came across a problem. When I change the scope of the search to SYS1, I see three copy locations listed: New Arrivals, Reference, and Stacks. However, the Concerto data includes several other OPAC-visible copy locations owned by SYS1 that don't display, including Children's Fiction, Fiction, Juvenile Non-Fiction, Non-Fiction, Special Collections and Young Adult Fiction. I would have expected all of those copy locations to appear in the filter as well.
