There's something I didn't want to mention before since I wasn't sure whether or not it was just a client side thing. But i've checked on different computers, so here goes.
Sometimes (though not always) the colour circles for Gallic systems aren't complete, sometimes being split into two or three parts. This doesn't affect the quality of the map in any way, but I wanted to check in case it was deliberate (since the sections of colour are frequently of equal size to each other).
