Can you try hitting F5 in your browser to refresh the UI and see if that date updates?  I've just tested this myself, and I see the same thing as you - the Last Refreshed date doesn't change when I do the refresh.  But then when I hit F5, it changes to the time I did the refresh.  I'll get a bug raised for this field not refreshing correctly automatically, but I'm pretty sure you'll find the actual refresh is working perfectly!
