Did you test it with that exact paragraph? It usually only starts breaking when the text you try to translate has any resemblance to an actual prompt message. In this case it is talking about the English language, which the LLM reacts to as if it is a continuation of the prompt rather than a text to translate
Yeah, no worries, I'm very grateful that you've put effort into this, it is something I should have setup myself a long time ago but I'm low on time myself and also intrigued to see how a community repository can evolve on its own. :)
