I found a similar unsolved discussion regarding CSV format document segmentation issues. You might find it helpful to check out the thread titled Help:CSV format document segmentation problem, which was last updated on August 8, 2024 [1].

In your case, it seems like the issue might be related to how the CSV parser is handling commas within fields. Ensure that your CSV file is properly formatted, with fields containing commas enclosed in quotes. This is a common requirement for CSV parsers to correctly interpret the data. If the issue persists, you might want to explore adjusting the CSV parsing settings or using a different delimiter if possible.

To continue talking to Dosu, mention @dosu.
