Flag won't show on my rides

When I initially set up Zwift I did not choose a flag. Later I went back to my dashboard and chose the U.S. flag but when I ride it still doesn’t show up next to my name. Is there something else I need to do to get the game to pick it up?

So I just went back to my dashboard and my flag was now unset. Set it back. Now it shows on my ride. So never mind I guess.
