I am trying to add "Transportation" style reference to change the display of my point symbols, but for some reasons I can't. When I am in Symbol Selector I select "Style References" and then check in "Transportation", but it doesn't add new symbols to choose from.
When I go to Style Manager the "Transportation.style" icon is grayed out, but at the same time I can go into "Marker Symbols" and I can see that symbols are there.
Please see attached picture.
Am I missing some files? If yes, where could I download them?
