There's another small translationmistake in here. Cheerilee says: "Like many ponies I wasn't born with cutiemark." Implying that some ponies are born with cutiemarks. In the original english version she says: "Like all ponies I wasn't born with a cutiemark".
Nothing dramatic, but worth mentioning.

Also, she asks "can someone explain to me why a pony gets its Cutie Mark?" instead of "when".
