some Enrico COT entries seem odd

cc @conceptofmind
Are these on purpose? Input strings look like they may not have been parsed correctly?

For example:
https://huggingface.co/datasets/conceptofmind/cot_submix_original/viewer/conceptofmind--cot_submix_original/train?row=505
https://huggingface.co/datasets/conceptofmind/cot_submix_original/viewer/conceptofmind--cot_submix_original/train?row=606
https://huggingface.co/datasets/conceptofmind/cot_submix_original/viewer/conceptofmind--cot_submix_original/train?row=607

Start by inspecting the three linked Hugging Face dataset rows, 505, 606, and 607, and compare their input strings with the surrounding entries. Determine whether the unusual strings are intentional or indicate parsing errors; the issue is complete when that status is established and any required follow-up is identified.
