All the models output mixed data (errors). The larger is the context, the bigger the probability to happen. And this is an inherent property of LLMs (the output is a statistical concatenation of text, the LLMs are an vectorial database filled statistically).

If you connect an LLM to pilot a plane with passengers, prepare the obituaries, because would happen sooner or latter, an undesired index got mixed and produced a mixed/wrong output. But here, the bigger mistake would be to let an LLM execute commands without human revision, aimed by the deceptive marketing around the A"I" (LLMs).
