MacOS Mojave: 10.14.5 EndCities are without lootchest

Every time when I create a new world and beat the EnderDragon I'm searching for EndCities but, they're without any loot chests. And I don't know why. But the EndShip has loot chest with the loot and Elytra. I think it's a bug of version. I'm playing on Latest Release 1.14.4.
