Incorrect error when I make a typo (mistake in word)

[Olga Tsebro]

When I write "coala" instead of "koala" it says:
Unsupported Language

Firefly only supports English at this time.Please edit your prompt and try again.

But it's typo(mistake), not another language.

Why its a fail? It´s an unsupported language because the word don´t exist in the brain of firefly, so its unsupported. 🙂
