Because they might just be Earth ponies affected by a Crystal Empire spell, just like the Mane 6 (and Cadance and Shining Armor and Spike) briefly got all crystally when the Crystal Heart magic swept over them. Assuming that that is the case would be speculation, but in my opinion so would assuming that there's a whole different kind of pony who just so happen to mostly look like Earth ponies with overzealous special effects. Future episodes might elaborate and solve the issue one way or the other.
