Crimean names are in Russian. :/
Whatever you may think of Crimea status, people in Crimea use Russian language dominantly. Why would you expect names not be in it? This sort of behavior you're demonstrating is exactly what contributed to recent Ukraine troubles. P. S. In Italy, cities in Sudtirol - Alto Adige marked in both German and Italian. That's responsible behavior if you want examples.
