What map mode are you use?
Just normal political map mode, why? My desert/wasteland has never displayed properly and that Syria is ruled by a dynasty that also rules somewhere else so it uses the normal kingdom name, if either of those were why you were asking?
Can I ask who is the purple state near you? It isn't the Byzantine Empire, since it has another shade of purple.
I think it was the Byzantines, to be honest. What shade do you think they normally are?
